The Moon is a surprisingly good environment for an airless body - its regolith can be used to build shelters from radiation and meteor impacts, as can the vast system of lava tubes; water & oxygen can be made by processing the rock. Nothing is wasted, except your comment which was on par with Vladimir Duthiers’.
COMPLETE waste of resources. It’s a rock, without air, food or water.
Probably a trillion dollars to establish a geodesic dome for 6 people.
