I find the idea lovely for the following reason: I am a great believer in the idea of competition, especially between nation states, and in the US, between states.

If California were to ever make such a dumb move (I'm 99% sure they wont'), they are going to create tons of opportunities for nearby states as all the rich folks will move elsewhere with their capital.

Please, California, keep on taxing the goose with the golden eggs.

Politicians should be playing more Sim City.
