Who is to say that we would work better in cooperation rather than competition? I think we have a larger sense of competition rather than cooperating with people. there will be those that wish to undermine the cooperation for their own personal gain, which creates a whole new sense of anarchy. I do like the thoughts of like minded individuals working in groups, which is sort of how communism got started. Living in "communes".
I feel like it is a good thought, but so was communism. Idealism in its purest form is a great thing, but nothing can be as simple and perfect as systems like this in my opinion.
I think that it could work but it could also just as easily fail. Theres no way to tell until somebody tries it, so I'm all for developing some ideas.
I admit I have no empirical evidence for my stance, but here is my reasoning: in order to compete, competing parties must spend resources on things other then direct progression towards their goal, thus reducing efficiency; while in cooperation, cooperating parties can spend all resources on direct progression towards their goal, thus acheiving maximum efficiency. Therefore, it is more efficient and effective to cooperate rather then compete. Regardless, here is an interesting read, as well as here. Note that neither represent my ideals or wishes, simply here as more food for thought. Also worthy of note: both of these were reactionary, meaning they arose in response to some opressive action or other. I do not think that's how anarchy will come about.
