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.

We actually did try something like in preparation of future colonization efforts. We called it Biosphere 2 and they were experiments to house a small team in a self sustaining environment. It didn’t really work out.
