I really don't see many multi millionaires sitting on Mars trying to do subsistence agriculture honestly and if some want to, they are welcome... You are missing the point. Capital funded the moon missions as well - just in that case it was the capital of the community you belong to, let's say your nation, so you feel involved. Nowadays NASA can't even put a human being into orbit any more - and that's not the fault of SpaceX. As a "public Common", everybody should be allowed to go there. That's not the same as to claim ownership, which indeed should be publicly and very well regulated.
