The fact that bombarding lithium with neutrons produces tritium that decays into helium 3 (this reaction is actually responsible for a good fraction of the yield of many fusion warheads, see Castle Bravo). And the helium 3 on the moon is A - on the moon, B - of such a low concentration that the total thermal energy possible to get from fusion of absolutely all the He3 present per cubic meter of the top foot or so of lunar soil is about a quarter that of the worst lignite coal on Earth. And lignite requires a hell of a lot less energy and infrastructure p...
