So these city states should be able to have whatever type of #government they want as long as movement was free between them? I can see that. It's not quite #anarchy, but it could work.
So some cities could be atheists and refuse to accept any creed and if you wanted your #God respected you could leave and go somewhere that agreed with you. That seems fair enough.
I'm thinking this through. So you could have libertine cities where #people were free to live polyamorously , because that would be the same. If you want traditional families you just go somewhere else.
And you would have Islamic and #Christian cities etc. I think I could buy that cheese :)
