Yes there is a debate between the Martians & the O'Neilians with Elon on one side & Bezos on the other, although recently Elon has become open to O'Neilian ideas.
It is looking like SpaceX intends to provide enough launch capacity for both to happen simultaneously.
Indeed, because of the timing of Mars launch windows only every 26 months there will be huge launch capacity available for non-Mars projects during around 23 out of 26 months.
