Been there, done that. It might be worthwhile to use Earth-to-Moon travel as a benchmark -- such as we used "crossing the Atlantic" or "New York to LA". Otherwise, what's the use? 1) I suppose we could build factories to make stuff too dangerous or difficult to make on Earth. But LEO would probably work just as well more cheaply. 2) Build a "Super Guantanamo" where "life without parole" has some real teeth. We might find LEO, Sealabs, and near-Earth asteroids more useful. Going to Mars would be more difficult and more imaginative.
