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 Rothbard[W]hich category of crimes does the State pursue and punish most intensely? [T]hose against private citizens or those against itself? The gravest crimes in the State's lexicon are almost invariably not invasions of private person or property, but dangers to its own contentment, for example, treason, desertion of a soldier to the enemy, failure to register for the draft, subversion and subversive conspiracy, assassination of rulers and such economic crimes against the State as counterfeiting its money or evasion of its income tax.
Murray RothbardIt would be an instructive exercise for the skeptical reader to try to frame a definition of taxation which does not also include theft. Like the robber, the State demands money at the equivalent of gunpoint; if the taxpayer refuses to pay, his assets are seized by force, and if he should resist such depredation, he will be arrested or shot if he should continue to resist.
