If anything, it seems like deGrasse came closer to giving team Space!!! what they wanted to hear than I would have expected, in that he left open the implication that nation states might develop serious interest in colonizing nearby rocks and would then very likely find themselves in need of contractors for various purposes; and enable some more fully private side activities.
The ROI of getting things into earth orbit is well established; and it has a correspondingly robust market, with more outfits clamoring to enter it. Satellites are all sorts of useful and need more or less continual replacement, repair, and so on. Nobody doubts that.
The technical feasibility of snagging asteroids and chopping them up is still in the more speculative stages; but that also has an obvious possible ROI if the technical challenges can be overcome.
The case for the moon or mars, though, isn't just a matter of corporate shortsightedness, it's a matter of "Please, tell me about the ROI, within, say, the next 250 years...". Planetary colonization would undoubtedly be cool; and might be something that a nation state would get interested in as part of a prestige contest(like, say, the last time we were at all serious about the moon); but nobody ever seems to have any plans, aside from vague references to Helium 3, for what would make lunar or martian living more cost effective than some sort of aggressive colonization of underutilized desert regions or something similarly unsexy. The bounteous iron mines of mars? The endless plains of razor-sharp, static-clinging, vitrified silicates of the moon?
