In fact among the various options available for an off-planet settlement, I find an enclosed pressurized habitat on the Moon the most plausible one. At least our orbit around the Sun doesn't change when it comes to our Moon. And we have some experience visiting it too.
FWIW, it's not about saving the species or terraforming at this stage. It's about setting up more space-stations first - which in my opinion would become transit/rescue points for longer hauls and hops at some point in time. A station on Moon sounds like a better proposition than throwing buzzwords like terraforming or considering ourselves capable enough to prevent extinction level event on Earth at this stage. Even the dumbest startup ideas have to go step by step.
