As Chomsky writes, anarchism has a "broad back". Human society incurs the burden of a "state", however minimal it is (state of nature, anyone?), and anarchists who pretend otherwise are fooling themselves (what color will stoplights be?, how much is a dollar worth? when will the meeting be?). This all turns on your definition of a "state" --- massive, centralized, dispersed, thin, temporary, etc. Any way you slice it, humans will always have to work together.

He does this only as a matter of pragmatics ("goals versus visions"). He has made quite clear the reasons he has done so --- to protect people from the ravages of, e.g., corporations. His ultimate goal is to dismantle all forms of unjustified power.
