"It is my contention that Rothbardian anarcho-capitalism is misnamed because it is actually a variety of socialism, in that it offers an alternative understanding of existing capitalism (or any other variety of statism) as systematic theft from the lower classes and envisions a more just society without that oppression. Rather than depending upon the the labor theory of value to understand this systematic theft, Rothbardian market anarchism utilizes natural law theory and Lockean principles of property and self-ownership taken to their logical extreme as an alternative framework for understanding and combating oppression. ... Murray Rothbard was a visionary socialist ... Because the market anarchist society would be one in which the matter of systematic theft has been addressed and rectified, market anarchism ... is best understood a new variety of socialism—a stigmergic socialism. Stigmergy is a fancy word for systems in which a natural order emerges from the individual choices made by the autonomous components of a collective within the sphere of their own self-sovereignty. To the extent coercion skews markets by distorting the decisions of those autonomous components (individual people), it ought to be seen that a truly free market (a completely stigmergic economic system) necessarily implies anarchy, and that any authentic collectivism is necessarily delineated in its bounds by the the natural rights of the individuals composing the collective."
