Should Mars have one martian colony, with multiple settlements, or should we recreate the nation states of Earth, on Mars. There's also the possibility of creating nation states on Mars, in much the same way as we know from Earth, but not necessarily corresponding with the nation states of Earth. Could be based on who's sponsoring the colony.
One martian colony, with multiple settlements would mean an independent Mars, under one martian government.
Recreating Earths nation states, could be an American colony, a Chinese colony, a Russian colony, etc.
New nation states, could be a SpaceX colony, a Boeing colony, etc
