The above is not necessarily true, H3 is thought to be the ideal fuel for fusion based power plants. H3 is hideously expensive here on Earth but relatively abundant on the Moon. So if a fusion based power plants is ever built, the H3 on the moon might make it profitable to go there. Also, if do not know what else is on the moon. So a blanket statement about nothing of value being there is rather foolish to make.
What fusion power plants? When they start building fusion power plants then your idea might have some merit, but currently there aren't any fusion power plants existing, under construction or even in the planning stage.
Also, if do not know what else is on the moon
Nonsense - we have an excellent idea of what is there
except rather deficient in the heavier elements.
