Proudhon was born into a level of State-induced poverty neither I nor anyone reading this can comprehend. But as an entrepreneur, he built a successful publishing business, whilst being an outspoken critic of the suffocating bureaucracy of late-Bourbon France.
Proudhon was never a Communist of any sort, and was never an advocate of state control of anything. He did advocate voluntary member-benefit mutuals at one point, which I regard with grave suspicion.
Proudhon was an outspoken critic of the various top-down innovations in "property rights" in his era. Like Machiavelli, he was a master troll and fond of pithy clickbait overstatements of his more nuanced positions.
Anarcho-Communism is just regular Communism, but where Commissars are allowed to smoke weed :-p
