Aha! So, in order to organize in an anarchic society, maybe we should form some kind of democracy where people get to vote on things.
Of course, even if most people are good natured, managing and optimizing trillions of dollars of budget is difficult, so it would be good if we could elect representatives that could work in a small community of anarchists who can devote their attention to understanding these issues, and voting on them. We could perhaps call them "Congress".
WAIT A SECOND. I GET IT NOW. Anarachy IS big government!
