Exiling the super-rich from Earth is an efficient path to space settlement, because each one of them will use his wealth to build his own habitat. None of them will want to share, and all of them will have their own ideas of how things ought to be. 100 multi-billionaires, 100 habitats, 100 opportunities to see what works and what doesn't.
