How did I miss this comment? :D Anyway... communism can only be achieved by the totalitarian rule of the state that needs to make sure no one has more. Total slavery to achieve total "freedom" is impossible. This is why every time it is tried, it ends in total slavery and death of masses.
If anarchy means freedom, then we should be free to value the people who create things we need more than the ones we don't. Others are free to value other people who create other things they need. Free to exchange your time, skills and value things... So "Anarchy" of Bakunin is a paradoxical bullshit. It is an oxymoron. It can never be anarchy if it starts from the principle that others rule your life.
