My Disagreement with Murray Rothbard
I have been working on a book based on my past blog posts. The current chapter deals with my criticism of Rothbard's historical work and the attitude behind his approach to it and other things, the view that political disagreement is ultimately war not argument (my terminology, not his).
At the end of the chapter, I point out that the question of whether Rothbard's work is honest is relevant to whether you should trust him but not to whether his views are correct and has nothing to do with our real disagreement. Here is my current draft of that part of the chapter.
---
Our important disagreement, about which I do not think he ever commented, had to do with differing views of how the law of an anarcho-capitalist society would be produced. His was that the law would be the product of libertarian philosophy. Since there was, in his view, one correct answer to what the law should be, everyone would agree and so all courts would accept the same law.
[I]t would not be very difficult for Libertarian lawyers and jurists to arrive at a rational and objective code of libertarian legal principles and procedures based on the axiom of defense of person and property, and consequently of no coercion to be used against anyone who is not a proven and convicted invader of such person and property. This code would then be followed and applied to specific cases by privately competitive and free-market courts and judges. (Rothbard [1965], 208[1])
There are, in my view, two problems with this. The first is that, as the history of libertarianism makes clear, libertarian thinkers disagree on many features of a just legal code. To take only the most obvious ones, some libertarians, such as Ayn Rand, support laws protecting intellectual property, others oppose them. Some libertarians, probably most, believe that abortion should be legal, since a woman is the owner of her body. Others argue that it should be illegal, since the fetus has rights that should be protected.
One might attribute these disagreements to intellectual error on one side or another, and that is probably how most of those involved in such controversies see them. But it should be obvious to anyone who has made a serious study of the law that there are many legal questions to which philosophy gives no clear answer. Consider, for example, the question of what the penalty ought to be for theft. If the convicted thief is merely required to give back what he stole, theft becomes a profitable activity, since not all theft is detected: Heads you win, tails you break even. So the penalty must be something more than that.
How much more? Rothbard’s answer was that the thief must give back twice the value he stole, but he never offered any convincing reason why it should be two rather than three or ten.[2]The rule is supposed to apply to all societies, but in a society where theft is hard to detect it will still leave the thief with a profit hence will not deter theft. That is one example of the problem, but any thoughtful legal scholar or law student could offer many more.
The second problem with the idea of deriving law from philosophy is that it ignores the problem of making it in the interest of courts to follow that law. In market anarchy, courts and rights enforcement agencies are private businesses. They can be expected, like private businesses in our society today, to try to maximize their profits. Rothbard seems to be assuming that, once the philosophers have determined what the law should be, everyone else will choose to accept it. That might make sense if one believes both that the philosophers can show what is right and that morality is such a strong force that, once what is right is shown, everyone will want to act accordingly. But if that were true there would be no need for law and law enforcement.
I have a different solution to the problem of producing libertarian law in a market anarchist society, one which uses the self-interest of the courts and their customers rather than ignoring it. In my version, each individual is the customer of a rights enforcement agency that sells him the service of protecting his rights and arranging for his disputes to be settled. Each pair of rights enforcement agencies whose customers might interact agrees in advance on a private court and agrees to accept its verdict in conflicts between their customers, an agreement enforced the fact that they are repeat players. If my agency refuses to go along with a judgement against its customer today, yours will act similarly tomorrow. Fighting is a lot more expensive than litigating and produces less predictable outcomes, so both agencies will prefer to keep the agreement.
Private courts are profit maximizing businesses, so want to produce the system of legal rules and procedures that rights enforcement agencies will want to buy. Right enforcement agencies are profit maximizing businesses, so want to use courts with rules and procedures that their customers want to live under. Individuals are choosing rights enforcement agencies, in part on the basis of the legal rules of the courts they patronize.
It follows that the private courts will want to produce legal rules that individuals want to live under, just as private firms in our society want to produce products that their customers want to buy. In our present political system politicians want to pass laws that voters approve of, but the voter is neither able to observe and compare alternative legal systems nor to choose among them, since his vote has a near zero chance of affecting the outcome of an election. Under market anarchy, the individual can see how the legal rules of different private courts are working out and can choose among them by his choice of what rights enforcement agency to hire. He cannot, of course, have unlimited choice, since they have to be rules that other rights enforcement agencies are willing to accept, but he has much more control, hence more reason to make an informed choice, than in our system.
It follows that the laws produced under market anarchy will tend to be welfare maximizing ones. If libertarians are correct, those will tend to be libertarian. There is no guarantee that the legal system will be perfectly libertarian. But then, there is no way to guarantee the outcome of any set of institutions. The reasons to expect the laws to be reasonably libertarian depend neither on philosophers solving the problem of deducing oughts from is’s or on courts and enforcement agencies acting on philosophy rather than self interest. Only on economics.

It turns out that Rothbard did comment, in at least one place, on the difference between his view of an anarcho-capitalist legal system and mine, as was pointed out to me by David Gordon, who I have been corresponding with in order to make sure I do not misrepresent Rothbard. David is at the Mises Institute, a Rothbardian institution, and has been very helpful.
But although Rothbard notes that I do, and he does not, assume that different courts may judge according to different legal rules, he does not deal with the central question of why we would expect the legal rules of a market anarchist society to be libertarian ones. His only answer to that question is:
"Within the anarchist camp, there has been much dispute on whether the private courts would have to be bound by a basic, common law code. Ingenious attempts have been made to work out a system where the laws or standards of decision-making by the courts would differ completely from one to another.7 [footnote to my book]But in my view all would have to abide by the basic law code, in particular, prohibition of aggression against person and property, in order to fulfill our definition of anarchism as a system which provides no legal sanction for such aggression."
That is an evasion — proof by definition. He sets up his system, courts adopt rules that permit aggression, and he gets to announce that it isn't anarchism, which has no effect on what they are doing. And by his initial definition it still is anarchy, since courts are not supporting themselves by taxation, hence are not governments. It just isn't libertarian anarchy.
If you find the argument convincing, imagine the same argument by someone on the other side. Someone says what he is in favor of is "Just Statism." You object that, for one reason or another, the state will not act justly. He responds that in that case it is not Just Statism, which is what he is proposing.
