To be fair, we went back multiple times, and india just put a lunar lander on the south pole. Lots of valuable scientific data about our closest celestial neighbor has been discovered through these missions.
While I see what you mean, systematic scientific research about the moon, carried out over decades by multiple countries, however imperfect, is far different than the hubris of a bourgeois dipshit getting himself crushed at the bottom of the ocean, because he wanted to see a glorified cemetery and thought safety regulations were for liberal pinko cucks.
