I’m not going into detail here, too tired, but I’ll say that I think that anarcho-communism has thusfar been utterly misrepresented in this thread. Here’s the wikipedia page. I have a particular soft spot for Kropotkin in my heart. I’ve written about how the left and “right” anarchisms are compatible and may well even complement each other. Any socialist anarchist who does not believe that their interests ultimately align with the formation of a voluntaryist world is sadly mistaken, for if their theories are correct, and if their system would come about anyway, it is in their best interest to see the free market world a reality.
I have to say that it’s interesting to contrast the left and right conceptions of the state, for socialists see the state as a tyrannical system which enforces capitalism, while the anarchists see that it is a violent institution which is evil exactly because it violates property rights.
EDIT
It should also be noted that I am talking about the strictly “anarchist” version of anarcho-communism, not the “Marxist” version of this tradition, which does require a change in human nature brought about by the new changes in the new production structure of socialism.
