Anyway space has multiple commercial benefits, and they have already done what nobody else did before: reuse stages, to lower launch costs. SpaceX can probably remain afloat while the master goal of going to Mars (and back) becomes reality, tho Elon Musk himself refuses to go, he sent his car for lulz...
Master goal? I don't care what Musk has as goals.
Just happened to comment that there was no business model for small groups or colonies on Mars; that's unchanged and cannot change.
Therefore, there will be no colonies on Mars. I could be wrong, just show the business model that would support the travel and colony costs for humans. But I don't see it for Mars.
