Anarcho-capitalism is easier to justify because it doesn't have to answer the question of "what about poverty, exploitation, and abuse?" with anything stronger than "too bad for you". It's a lot harder to explain how you're going to eliminate material and social hierarchies without some form of legal hierarchy, which is why left anarchism tends to exist more as an organizing principle and a tendency within the broader (socialist) left than as an independent political movement.
