In the future the United States of America will probably have a Mars colony and most of the futurists and the people that talk about colonizing Mars have stated that there should be no boundaries and no nations. In other words everyone is part of the human family and no one owns the real estate on another planet.
Can humans survive with those current rules? We shall see, but that is what they're planning today. After all, if one nation gets to Mars first and puts up a colony they could in fact try to say they own the planet but this wouldn't be fair because within 100-years all nations would have visited the red planet. And many of them would have colonies both above and below ground.
This brings up another very good question. In the Constitution you must be born in the United States of America to run for president of the United States. But what if you were born on Mars? And there are no nations on the planet? Could you still some day when you grow up run for president on earth? Our Constitution specifically states that you could not. But will this law has to be changed in the future? It might.
In fact, there might be some very interesting case law on this brewing in the present period, which may indeed cause that rule to be changed, or make that rule so air-tight that a Mars colony baby born of earth born parents; one or both of which may be US citizens; would not be able to run for United States president. There is a constitutional crisis brewing in the future.
