Governance

Governance by abundance. Everyone is expected to contribute to an economy. If you don't, you're out. Simple. You pull your weight, contribute, no welfare state. People do things out of internal motivation. This is a rigorous condition of skill and wisdom, not a hippie getaway.

Major problems with this, however. Most people aren't evolved to look beyond their selfish interest. So it may be that we won't be able to find the 30 people. If that's the case, we'll go with less, or create more stringent governance. The latter is not preferable to me, because it starts to get people out of voluntary action.
