Playing Devil's Advocate here, but what's the justification?
Off-planet, you can survive if the Earth turns into grey goo. Not so
here. Merely preparing for off-planet has some merit, but not much:
you run into conditions that are neither at your chosen off-planet site
or in normal Earth habitation, and have to waste (from the end goal's
viewpoint) at least some of the effort you spend adapting to them.

Maybe if there were some economic motivation? Say, you find a way to
manufacture stuff, or a kind of therapy, or some mineral extraction,
that can only/best be done at the target site? (The first and third
have to answer why human presence, and not just robot presence, is
necessary; this usually involves something that robots can not do, or
at least not do well given current tech.)
