Well, if there is water on the moon, there is oxygen on the moon. A LOT, apparently.
Did we waste all that money developing astronaut life support systems? Could we have sent them there with a picnic basket and a six-pack of Pepsi?
And also hydrogen. By placing a small nuclear reactor on the moon, we could produce oxygen for breathing and hydrogen for fuel by breaking down the water. Perfect for a mars mission, with a lunar launch pad with a fraction of earth's gravity to escape.
Since each pound of material costs $10,000 to rocket out of earth's gravitational pull, the discovery of large amounts of water resource on the moon is worth trillions of dollars, if not quadrillions of dollars, as a launch point to other planets.
There are actual reports claiming to have seen our folks living there running around loose outside of dwellings without helmets.
