the most exciting thing about Startup Cities, Network States etc is that there are many ways society can function better but an extremely limited ability to try new things with Nation Stated full of millions of people.

Most new things fail while a few breakthroughs completely change things for the better.

So in Startup Cities, groups of people can opt-in to try something new and if it works those breakthroughs can be brought back to established states.

The second most exciting thing is that Nation States are failing before our eyes and without breakthroughs we are going to have to learn to organize and live together in new ways.
