The only reason to blow trillions upon trillions of dollars chucking meat-bags at anther star system to effectively never hear from them again is ideological.
Once you get that into the mix, then it makes just as much sense for Martian-bound people as space station.
If anything, I think it more likely, because more station kids would just ask, "Why go anywhere? What's wrong with the vast space just a little further out than 'here'?"
Planet-bound/obsessed people would focus on the few in this system and the many "out there".
