    It would be nice if it happens someday, but no one should rely upon it as a matter of faith. We're all stuck here, together. We evolved to live here. We need people not to give up on our only home.
    So if you move to another city, you're "giving up" on the current one?  The European colonists who came to the New World were "giving up" on Europe?  The people who first left Africa "gave up" on it?  We "gave up" on caves when we started building our own shelters?  Our primate ancestors "gave up" on the trees?  Wuh?

      people who think that civilization on earth is inevitably doomed (within the next century or two), and our only hope is to move off-planet. That hope is highly improbable, and if people who rely upon it therefore use that as an excuse to themselves not to take action to improve life here on Earth, that's a dangerous dynamic.

      Government and laws are the agreement we all make to secure everyone's freedom.

        Earth is certainly not "inevitably doomed," except billions of years from now when the Sun expands.  It's not even probably doomed.  It's just things will get a lot harder if we fail to address the challenges we face, both natural and self-inflicted.

        However, your claim that making human life multi-planetary is "highly improbable" is far removed from the reality of economic and technological processes already unfolding.  If civilization does not end in this century, people will be swarming the space on, around, and between Earth, the Moon, and Mars.  And that statement isn't based on some rosy optimism or Space Age historiography, but simply on economics as it's already unfolding.

        Thirdly, I reject your premise that human expansion into the solar system somehow entails neglecting Earth.  That's never been the reality of colonization.  Diaspora to the New World has been overwhelmingly beneficial to countries of origin, both economically, psychologically, and culturally.  Frontiers give people hope and options, stokes the imagination, inspires new ideas and approaches even among those who remain firmly rooted in the Old Country.  The same dynamic will play out with respect to space.

        Pour yourself into the future.
