I agree, but I think we're a ways away from it right now. We'll probably see people trying to really colonize Antarctica and the Oceans first.

I think there's gonna be people volunteering to colonize even if it's a net resource loss. Exploration and doing cool shit could be seen as a consumption good

It might eventually make sense, but not until we're fantastically wealthier.

I don't think colonization makes sense in the near-term because the most inhospitable parts of the Earth are still almost infinitely more hospitable than anywhere else we know of. 

There's also no reason to send significant numbers of people to the places that are economically relevant.

Long-term, though, there are amazingly cool ideas for how to build transorbital habitats that could comfortably carry enormous numbers of people between worlds and lots of ways to comfortably settle any world.

There's a YouTube account called Arthur Isaac that covers a bunch of these. His voice is pretty distracting, though.
