"i believe there are market anarchists who are not capitalists,"
i know there are those inspired by mutualism, agorism, etc, who define themselves left-libertarian or left-wing market anarchists contra the so-called 'anarcho' crapitalists. broadly, they are far more concerned about social issues like racism, sexism and poverty, as well as ecocide, than the lew rockwell/mises crowd...which isn't at all concerned.
'Economics/markets makes my brain hurt.'
indeed. economics seems to me one of the worst of the prevalent miserabilist tendencies. it (supposedly) reduces everything into units of manipulation, 'things-in-themselves,' while presenting itself as 'the way things are,' fact (aka 'reality'). yech. a ready-to-hand example of nietzsche's famous note (and famously quoted out of context) 'there are no facts only interpretations.' economics of every stripe depends on the large context of relations, perspectives, meanings, senses, we label as 'worldview.' in the case of economics, it seems always to entail a much reduced, impoverished, context.
anyway, for some heavy head-hurting there's this.
edit for added thoughts.
