Why not halfway between us and the moon? It could be an easy-to-reach halfway point for the Moon, a refueling station and very-low-g launchpad other points, internet relay base, and also have commercial, industrial, and housing areas.

This could be an interesting new step in human modification of the environment - "orbitforming" (like terraforming?) a better solar system. It's like razing a hill to make way for farmland or better city building conditions.

An asteroid that's easy for vacationing billionaires, mining companies, and highly-pollutant industry to reach would be a great next step for humankind.
