Is it about perceived ethics and population? It would be too difficult to stand by on the same planet thriving while the rest can see it up close? Safety, security etc.?
Is it as simple as planetary colonization being about exploration and very long term advancement more than the disaster escape scenario in my mind?
Or, am I completely missing something else?
EDIT to clarify that I’m not suggesting any artificial habitat that would be lived in now or in the near future, but in the bigger picture of humans needing to adapt to the changing world.

There is essentially no need to colonize Mars. Aside from a planet killing asteroid, there is no scenario where Mars is more habitable than Earth. Earth in the middle of an ice age and covered in radiation is still more hospitable than Mars. Having a breathable and heavy atmosphere is a really big deal, and we aren’t losing that anytime soon.
