Many seems to think that anarcho-capitalism of the Murray Rothbard and David Friedman differs only in arguments, the former using “natural right” ones and the latter “consequentalists”. I think that diversion is much more fundamental, and that their versions of anarcho-capitalism are different.
The difference is simple, and it’s about the law. David Friedman supports polycentric law, while Rothbard is for “natural law”. In polycentric law, the property owners decide what set of laws is used in their lands, and this is the definition of anarcho-capitalism used by Friedman. Rothbard states, that an area which uses “libertarian ethics” and non-aggression principle, is anarcho-capitalist. But according to the definition of Rothbard, Friedmanite version is only partly anarcho-capitalist, basicly in those areas where property owners choose to follow NAP and libertarian ethics. Other areas are not, according to Rothbards definition. This is Rothbard in For a new liberty:
It is now clear that there will have to be a legal code in the libertarian society. How? How can there be a legal code, a system of law without a government to promulgate it, an appointed system of judges, or a legislature to vote on statutes? To begin with, is a legal code consistent with libertarian principles?
To answer the last question first, it should be clear that a legal code is necessary to lay down precise guidelines for the private courts. If, for example, Court A decides that all redheads are inherently evil and must be punished, it is clear that such decisions are the reverse of libertarian, that such a law would constitute an invasion of the rights of redheads. Hence, any such decision would be illegal in terms of libertarian principle, and could not be upheld by the rest of society. It then becomes necessary to have a legal code which would be generally accepted, and which the courts would pledge themselves to follow. http://mises.org/books/newliberty.pdf page 282
Also, this is what Rothbard says about “Friedmanite anarchism”:
The free bankers accept a kind of David Friedmanite anarchism, where there is no law, only people engaging in exchange and buying people out. If you have a group that wants to kill redheads, the redheads will have to buy them off if they value their hair. I think this is monstrous, the kind of anarchism would indeed be chaos. Just because there is a demand for something doesn’t mean it should be fulfilled.

So if Catholics restrict abortion in their lands, that’s not anarcho-capitalism according to the Rothbard. Same goes for Jewish regions and circumcision. Hans-Hermann Hoppe has supported the idea of some kind of polycentric law(http://mises.org/daily/5270 ctrl + F + catholic), but holds still the Rothbardian viewpoint of ethics. This “Hoppean” synthesis seems to be quite common in modern days, where libertarians think that polycentic law is good and property owners can choose any laws they want, but through some mystic way most or at least big minority of property owners start to follow Rothbardin NAP. This wasn’t Rothbards idea, and it seems that ideas have evolved among the Austrians since the days of Murray.
But few questions about the polycentric law - what if some property owners actually do what Rothbard feared, and start to punish redheads with death in their property? For an adults this isn’t a big problem for a long time - they can move out and/or never move in. But what if property owner decides that you can’t leave? And what about children? What if property owner decides, “In my property, all newborn shall be automaticly citizens of my property, even without contract”. In Friedmanite anarcho-capitalis, there is no-one to stop him. This would naturally be a birth for a new state, because every new generation born under that property are basically under the authority of the property owner, and he could create laws denying the exit from his area. So if anarcho-capitalism is Friedmanite and property owner has total control over his land, what stops it from evolving to a new state?
