Out of the trillions of galaxies out there and the trillions more solar systems, it is very likely that at least some of them have multiple planets with habitats suitable to whatever intelligent life evolves there. In that case, an interplanetary civilization would merely require reaching the other habitable planet, not trying to change its environment. |

This assumption is exactly what I am challenging: that there is such a thing as "general suitability" to life.
We should be open to the possibility that a living system is only compatible with the specific circumstances it emerges from. We've seen nothing to indicate either way, of course, not having seen any other life. But we should not so comfortably assume it's a transferrable process.
