A libertarian who views the abolition of the state as necessary for a free society. Unlike anarcho-capitlaists, an anarcho-libertarian does not seek anarchy as the ultimate goal, but rather as just one facet of a free society.
Libertarians come in all sorts of varieties. Some see the state as necessary for liberty and others see it as a direct violation. Followers of anarcho-libertarianism think the state must be dissolved as part of the process towards freedom.
