It would help, some, for it to be actually possible for a Mars colony to exist, and then maybe to survive at all. But there is thus far no reason to expect that. Certainly not by relying on Starship/Superheavy, which is so far from adequate it is comical. Starship might be adequate to keep a small moon base operating. That would be an achievement.
