Subterranean anarchist currents once agains surfaced in the 1960s...We will sketch its initial impulse in the 1950s, the creation of a broad critical movement in the 1960's, its differentiation into right and left tendencies, and its final shattering into various anarchist splinters. These ranged from Anarcho-Capitalists who desired the organization of society solely on the basis of a "free market" to Anarcho-Communists who sought an individualized society of decentralized communes.
The Anarcho-Capitalists, who had more of a historical sense, did occasionally cite past anarchists like Spooner and Tucker as "the forefathers of modern libertarianism," but only a few individuals like Murray Rothbard, in Power and Market , and some article writers were influenced by these men. Most had not evolved consciously from this tradition; they had been a rather automatic product of the American environment.
Today individualist anarchists in the US call themselves anarcho-capitalists or libertarians...
Although part of the classical liberal tradition, contemporary anarcho-capitalists are descendants of nineteenth-century individualist anarchists such as Josiah Warren, Lysander Spooner, and Benjamin Tucker."
Anarcho-capitalism, in my opinion, is a doctrinal system which, if ever implemented, would lead to forms of tyranny and oppression that have few counterparts in human history. ... I should add, however, that I find myself in substantial agreement with people who consider themselves anarcho-capitalists on a whole range of issues; and for some years, was able to write only in their journals. And I also admire their commitment to rationality which is rare though I do not think they see the consequences of the doctrines they espouse, or their profound moral failings.
