All of the services commonly thought to require the State-from the coining of money to police protection to the development of law in defense of the rights of person and property-can be and have been supplied far more efficiently and certainly more morally by private persons. The State is in no sense required by the nature of man; quite the contrary.
Murray RothbardI define anarchist society as one where there is no legal possibility for coercive aggression against the person or property of any individual. Anarchists oppose the State because it has its very being in such aggression, namely, the expropriation of private property through taxation, the coercive exclusion of other providers of defense service from its territory, and all of the other depredations and coercions that are built upon these twin foci of invasions of individual rights.
Murray RothbardThere can be no truly moral choice unless that choice is made in freedom; similarly, there can be no really firmly grounded and consistent defense of freedom unless that defense is rooted in moral principle. In concentrating on the ends of choice, the conservative, by neglecting the conditions of choice, loses that very morality of conduct with which he is so concerned. And the libertarian, by concentrating only on the means, or conditions, of choice and ignoring the ends, throws away an essential moral defense of his own position.
