Will respond to just one of your points. Don't think we will be going anywhere with the rest of them..

>Going to another planet, and learning how to survive there, including how to properly manage and keep an environment pristine and survivable in a sustainable fashion...

We are not able to keep ourselves from completely ruining the environment here on earth. That we would be able to "learn to keep the environment on mars or what ever world pristine and survivable in a sustainable fashion" is just wishful thinking.

What I think is that the short sightedness we have, as a species will be our doom. And worse, our core system of existence, require people to be more and more short sighted.

So, as much as we might not like it, unless we, as a species, learn to cultivate sustainable habits, we are going to be selected against in this race to become a space faring species. We just might end up going to Mars or a couple of other worlds. But that would buy us some time, but that is about it be it.
