Yes, there's clearly hurdles on the path but I think they're well worth figuring out how to clear. There's multiple reasons why but one that stands out in my mind is the sheer difference in trajectories between a species that embraces spacefaring and comes to live on multiple worlds compared to a species that remains confined to its point of origin. In the long term, the former of those two will eventually fan out to other star systems and explore countless more modes of existence, structuring of societies, ways of expression, avenues of science, etc than the latter can ever hope to. Staying put stymies potential to an extent that's difficult to even comprehend.
