I’d love to do this, but we literally don’t have the energy budget for that. At least, not for everyone. Rockets require crazy stupid amounts of energy for relatively small amounts of mass, just to leave Earth’s gravity well. Nevermind that space is an incredibly hostile environment requiring technology we don’t even have yet, or that our next best bets for settlement (Mars and Titan) aren’t much better. We’d be far better off terraforming the Sahara.
