Just playing devils advocate. You can't kick people out because of existing contracts / promises based on citizenship. Currently borders are leakier for big corporations / the rich, then they are for the individuals / poor. Corporations do have walled gardens across borders. A google employee is better off than a us citizen on average regardless of physical location in Palo Alto or Hyderabad. If you did have open borders, you would probably end up with more privatized cities where all the land is spoken for by rich people. Eventually countries would be replaced by cities or corporations... I think we are kind of headed that way anyway in effect.
