Re: Economics 'The belt' would best be mined by automated, semi-remote controlled machines. The Moon offers a good target to fire those resources at (aim to roughly keep it's orbital momentum the same), a low but not No G fab area with easy access to 'free' vacuum, and is usefully close to Earth orbits. Mars... I can't really think of any particular thing it does better offhand, that couldn't instead... Lagrange Points (L4 and L5) offer areas usefully distant from Earth for scientific and world-ending-event backup purposes, have a relatively low escape velocity, and are "safer" in that they draw masses to stay near them. This would be a great place to park a large rock (for shielding) and core out the inside. https://en.wikipedia.org/wiki/Lagrangian_point https://en.wikipedia.org/wiki/Lagrangian_point
