If all this is about bringing back moon rocks for sale, I think the
bottom would drop out of that market fairly quickly. A handful of
multi-millionaires would be willing to play plenty to have the first
privately owned moonrock. Maybe the second or third. But who would
buy the ten thousandth, for any price at all? Maybe for one dollar,
or other souvenir shop chump change.
