“So, who should have the right to acquire property in space? My answer: those who have the financial means to get there, develop, and use the land. For instance, if SpaceX succeeds in reaching Mars and starts to build permanent settlements on the red planet, then the ownership of land should go to SpaceX first. Not of the entire planet, of course, but of a practicable area, for example the size of Singapore. The surface area of Mars is 200,000 times that of Singapore, so SpaceX would initially only own 0.0005 percent of Mars. That would be enough to develop multiple settlements, but not so many that others would no longer have a chance.”
-Statement by Rainer Zitelmann, a historian and sociologist, in his Reason magazine article titled “Why You Can’t Settle Mars or Colonize the Moon Without Real Property Rights.” You do not need to agree with his conclusion, but he discusses a timely topic. The Moon Agreement and Outer Space Treaty may need to be revisited now that the idea of permanent settlements on the Moon and Mars are not simply science fiction, as they were in the 1960s and 1970s when these provisions were agreed to (and not by all nations, keep in mind).
