Jeff Bezos' Vision: Trillion Humans in the Solar System

This one sentence nails everything wrong with the expansionist mindset: we could have a 1000x as many active geniuses as we do now, and all that dynamism and intelligence with our current population if we could just figure out how to better organize the society that we have, stop wasting resources on things that don't matter (like most of the crap Amazon sells), and stop grinding people into dust (the the people toiling in Bezos's warehouses, for example) for the sake of short-term gain, vindictiveness or simple neglect.
That's where our future lies. Not in throwing in the towel, and simply scaling the current social model out by 1000x.
But before we go ahead with mass colonization, could we maybe prove that we can take care of _this_ planet, reach sustainable living and responsibility stewardship, and stand half a chance of not completely junking up the rest of the planets too?
I understand the reasoning against this line of thought and I'm well aware that "not putting all eggs in one basket" is a common motivation for investing in off-earth colonization. That said, I took Seveneves to be a fun, occasionally tedious story of how crappy it would be even if we did everything "right" on short notice. Starting the process before we have a deadline would theoretically help to avoid the crunch that led to much of the issues in that novel.
I want to hear more about that as an alternative to terrestrial limits to growth based paradigms.
The cost to keep one human alive in space is logistically incredibly expensive. It'll get cheaper the more infrastructure we put up there, sure, and eventually we may see space-based colonies become self-sufficient. But I don't see it happening any time soon.
Meanwhile, current projections suggest that ~2050, human population is going to get very hard to maintain. Even if we could get 100,000 people living in space by then it would be a drop in the ocean.
