I think they should consider the society into which they would move.  Best enjoy the walls in their gated community, armed response guards and take the time to decide on the right firearm for their 'home defence'....

Taxes pay for the type of society in which you live.  

If you do not pay taxes you will end up with the rich living in fortresses with armed guards (they are called castles) and in constant fear.  Just wait until Trump eliminates the estate tax (in the first quarter), this will create a perpetual ruling class, we can call 'royalty'....and they will live in 'castles'...welcome to the 'American Dream'....
