Not sure who Maknho is so thanks for the name drop I'll check their work out, but as far as I know, Bookchin was a lefty anarchist. I always assumed his later 'libertarian phase' was just another label that he'd eventually disavow as well but that his critique of the state also went alongside his critique of the market.
Can you refer me to other libertarians who are particularly anti-market, in the American context?
