So how are you going to make this country populated by ‘scientists, doctors, and professionals’ - are you going to kill or expel the 1/3 red staters? How are you going to maintain order without police or prisons and independence without a formal military or militia? If you cut out the ‘red’ areas from a state and have a little city-state, what are you going to do when the lower classes start to get discontent, or when you have crime waves to deal with? Especially, what will you do if those hated ‘red staters’ close down their prisons and send the worst of the gangbangers and whatnot right back into your city?
All of this ‘blue state secession’ stuff is pure fantasy, there’s not a plausible path for how you get there (unless you start mass murder or mass expulsions) or how you maintain a functional country with such hostile neighbors. And that’s not even getting into things like how desperately dependent Blue California is on a bunch of Red areas just to have a functioning water supply!
