Are you going to be a dictator and get to tell people that they can not wander the globe?  Are you going to tell them exactly how to live?  What if more people want to live in those communities than you hope for?  Pipe dream at best.   I, also, for one do not believe your worst  case projections.   I seem to remember people of your ilk saying everything was going to come crashing down on 1 Jan 2000.   I also seem to remember something about a coming ice age and that we were going to be all out of oil by now.
