Resilience. Being multi-planetary means your species is fundamentally protected from almost all catastrophic events. Having presence among multiple stars systems would mean not even planetary level destruction would be a threat to a species. As it currently stands humans are still very much in a precarious situation as an errant asteroid, even a decade away, could mean game over for all of humanity.

The amount of energy required for to cross the intergalactic void is insane. Our local group is about 3 megaparsecs in diameter the Milky Way is around 32 kiloparsecs in diameter. Asteroids aren’t a problem if you can expand to other solar systems yet alone across galaxies.
