Can Branson Charge For Flights In An Experimental Aircraft?

I haven't followed this argument and I'm not going to go back and read it so
if this has been mentioned before please ignore this comment.

The FAA is an American regulatory agency. They have absolutely no say in
anything the rest of us might do, thank God. If Branson is interested in
investing huge quantities of cash into making something like this happen I
doubt some piddly little American agency will stop him.
