Earth has gravity already. The people and building materials are here already. Even if unbreathable the air is still air and not vacuum.

Yes, that's one reason I keep suggesting the aerostat colonies. They boot strap and can even touch the ground when absolutely necessary so you can have hundreds of thousands of people board in a day if necessary, like filling up a huge stadium or speedway. It might even be easier than going to the sports venue since there's no particular concentration within sight of a common activity.

Not nova, just red giant.
