it's literally the unironic exact opposite of communism, and you're thinking of socialist anarchism, that pretends to be anarchist but the way it gets rid of hierarchies means it obviously needs a state and therefore it's unstable
anarcho capitalism still retains hierarchies but gets rid of the state, basically having companies doing everything in place of the government since the existence of the government itself is aggression since the only way it can function is by using taxes, and taxation itself is theft since we don't pay for it voluntarily
