One of the problems for the anarchist movement is the anarcho-capitalists. Even if this is not such a terrible idea in general, it is not clearly the kind of anarchism to which one should strive for. There can not be any free will when there is a market. The market will act as a regulator. At best, people will simply obey him, and not really want to respects others will. The market is the same regulator in the economy as a state in politics. If it is already for that matter, then the market, which it is just the same government but in another arrangement.
