Humanity is not going to live on other planets; not in the 21st century and almost certainly not in the 22nd century either. Hell, making a perminant residence on Mars or Veneous or whatever would be a centuries long undertaking – the sort of thing well beyond us. At best, at the very damn best, we can lay a foundation that may one day a very long time from now perhaps maybe have a chance of even starting such a thing. And by “lay a foundation” I mean preserve, restore, rehabilitate and care for the biosphere. If you really wanna see people in space, we need more regulation. Far, far more.

even if humans could organize and design fully self-sustaining habitats that did not require a biosphere or extensive body modifications (unlikely), there would be little reason for us to ever bother with the energy expenditure of transitioning into or out of a gravity well ever again.
