Moreover, I agree with the fact that unfree markets (or even free market in the agorist sense) are a tool for coercion. But free markets, in its anti-capitalist sense, doesn’t force any coercion (okay, it’s possible to market yourself even in this free market setting, I admit it). But I don’t see how a non-market scheme (even if I’m not so sure that your non-market is not a form of free market) could evolve from unfree markets.

“Present-day free-market anticapitalism appears to be the assertion that the non-aggression principle, if actually realized, would produce rather different outcomes.”

Yeah, I think baseline mutualists go no enough far in their reasoning, and that’s an issue. Non-aggression principle is not sufficient to obtain this outcome.
