Its components are voluntarism, non-aggression and property as a simple concept, because otherwise taking anything forcibly from another person is not clearly aggression. Property on knowledge is generally not recognized in ancap (so no trademarks and patents), property on resources in usually disputed in ancap (because you haven't made those resources and have the same right to them as everyone else).

You have also answered the wrong post, this one was not about ancap at all (are you a buggy bot or just came here through my post history?).

Actually the opposite - some compromise between Marxism and our world which for me personally seems better than all those complex wealth redistribution systems. Simply abolish inheritance of a kind of property that some call means of production, some something else etc. Then that material value may be used in some socially useful way, while the society becomes much more egalitarian and market mechanisms start working again. Naturally this means that companies won't grow big, so cooperatives will become plausible form of organization.

It's some kind of Trotskyist socialism, I'm just trying to extract it from my memory of the short period when I was excited by such stuff.
