> There's nothing there we can't get on Earth, 10x cheaper. It's not too big a stretch of imagination to consider producing oxygen on the Moon from rocks and sending it to LEO for refueling Starships - this activity might get useful enough if we're going to use Starships to fly someplace more distant than the low Earth orbit. And Moon-originated oxygen has an energy advantage over the Earth-originated one.
