I agree. It's astronomically expensive to set up humans on the moon, and much more so on another planet. Think of the much much more productive ways that money could be spent here at the bottom of the gravity well. As for asteroid mining, aren't metals available here on earth too, at a fraction of the cost? How about an R&D effort to make batteries and other technology out of easily-available metals here? Wouldn't that spending yield useful products much more cheaply than trying to get them from out there in the sky? We have to stop reading science fiction and taking it as prophecy. The case for seeding our species on another planet makes no economic sense.
