Given that humanity has only existed for ~200,000 years, and the threats you've mentioned are unknown but likely millions or billions of years in the future, is it fair to say it's a "temporary paradise?"

If we could live another ten, one hundred, or a thousand of humanity's lifetimes, that's not temporary in any meaningful sense.

To put it differently: making plans today for the earth's demise due to the sun's expansion is a rather extreme case of premature optimization.

It’s the next frontier and an area for expanding our technological prowess, even if we disregard the doomer psychology aspect of it. We have so much shit to do to even mine the asteroid belt that the next 100 years will look as different from now as we do from the Middle Ages. Not to mention when even further in the future we decide that interstellar travel must be attempted.
