Even if you could make travel to Mars as cheap as intercontinental
air travel is today, and had the same number of spaceships, with the
same capacity, as all existing wide-bodied jets, can you even remove

continue to breed after arrival?)

The answer to that one is yes. We currently move more people per day
in airliners than the net world population growth.
