Government is Irrational.

[Tonus]

Shunning an uncooperative person is an act of government, at least from the shunned person's point of view;

That wasn't my point. I was commenting on the claim that we're "douchebags by nature." I believe that humans are social creatures by nature, and that most of us see the benefits of cooperation and of putting the community above the individual. The ratio of douchebags is, IMO, very low. But given that we are social creatures who create communities, even a small ratio of troublemakers is damaging to the community. Thus, we create governments, be it on a loose and communal scale or on a large and rigidly organized one.

Koolay's point appears to be predicated on the idea that we can continue to refine humanity until so few disruptive people are left that they can be rendered ineffective. I think that this view is unrealistic; you only need a very small group to wreak considerable havoc in a community, and in a world as interconnected/interdependent as ours the damage would spread quickly.
