So you are going to create a free society by buying a bunch of land from a violent government? People who are rich already have freedom to do whatever they please. This is only different from paying taxes in that you are paying a lump sum up front instead of paying every year. There is no guarantee that you will be left alone from violent governments. I do agree that you should use your wealth to promote your principles so maybe it is a good thing and I'm sure it would be nice for the rich people that get the privilege of living there.
