The fact that governments grew out of a need to regulate social cooperation does not mean that governments are the only, or even the best, method of meeting that need. We have learned a lot in the past 10,000 years about the downsides of using governments to fill this need; that experience means we are not in the same position as the people 10,000 years ago who first formed governments. Governments exist today mostly out of inertia; that's how we've always done it. Maybe it's time to re-examine that belief.
