Von-numan machine style exploration is the major reason to fab anything in space. It doesn't even need to be the latest process or anything super special; it just needs to be reliable and operate within the power budget. Imagine if we surveyed the asteroid belt and sent robots to likely areas to mine for resources. Then returned them on kinetic delivery trajectories that were designed to accelerate the moon's orbital velocity (tidal effects or something else are probably slowing it down slowly over time? I forget the details) and keep it balanced. We'd probably want water, metals, and anything useful for chemical reactions sustaining life, industrial production, or high-density single use fuel. Hydrogen and Oxygen could be obtained from ice via electrolysis, which solar power could provide during the day.
