Arbitration is a purely voluntaryist means of settling societal disputes. In an interesting insight on means and ends, Bruce Benson, Murray Rothbard, and others have noted that customary law and the private sector must provide the underlying foundation of property rights for the free market system. It is impossible in the nature of things for a compulsory, monopoly legal system to supply the laws required by a totally competitive system. "Politically dictated rules" and statutory law are "not designed to support the market system; in fact, government-made law is likely to do precisely the opposite." A coercive, non-competitive judicial system simply cannot be made to define property rights because it is based upon the supremacy of the political sovereign. In its absence, a customary law system based on private property and personal property rights would evolve, and arbitration would become one of the major ways of settling disputes.
