A small note, just to descend from the dream to reality: lithium is already expensive. Mining lithium in space means making it more expensive than gold. Even if we can source a hyper-abundant source of lithium just on the Moon it's price would be so expensive that's useless. Not only, the quantity we can mine will be ridiculously small. Space mining might be an option in 200y IF we are able to find ways to escape Earth gravitation with cheap and easy manners, otherwise is just a dream game of some who dream a "private space" to start a new "Alaska-like Gold Rush". Such dreams must be annihilated from the start for the sake of humanity. Just the dream of private Moon/Mars colonies should be allowed only when single individuals can form a small society, buy a transport means, start a colony independently under their own State's laws. Otherwise those colonies will NOT be colonies like the west rush in the USA but dictatorship where the private holder can do essentially anything shielded by the fact that State's laws we have are valid only on Earth. That must not be happen. Beside that: we can't even really know how much minerals in general we have in the Earth crust. We have estimation, reasoned, tried a bit, but nothing really certain so before working on something we should have been framed the scalability up front or live them as experiment.
