other planets (and free-floating colonies) can be made habitable (with time and significant cost and work), and the technology gained in doing that can help with repairing the damage we've one to our own planet.
Experimenting with the biosphere and climate of Earth is guaranteed to have short and long term consequences, and its better for the planet's population if those experiments and technology development were done somewhere else where there is zero chance of killing most of humanity

No they can't. It's easier and cheaper to build bunkers on Earth by an order of magnitude. Stop believing Sci-fi. Earth bunkers could survive anything practically. It's not even that difficult.

You can certainly dig a hole in the ground and hunker in there for years, even grow food and recycle everything.
However you can never collect more resources than what you take down your hole, and all of the technology you use to hide down there will wear out.
an underground bunker is just a guarantee of a slow death for the inhabitants, it certainly provides zero future for them

You can wear space suits on Earth just like you can on other planets. So you can definitely go out and gather more materials. You are naive. It is also easier because there is still some atmosphere that you can filter to provide breathable atmosphere.
