That sounds great. I'm just not sure it's compatible with current nation states.

As a first step we could perhaps agree that individual people could come and live in Europe and participate in our democracy?

I think physical presence is actually quite a good precondition for participation. At least people physically present have some skin in the game.

With a transition period, I'm not sure I'd have a big problem cutting many other links with non-democratic countries. I agree with your ideals but all evidence is that trading and communication links and other sources of interdependence will be abused. We need to have policies which respond to that.
