ELI5: Why hasn't anyone else been to the moon? It seems like something that super rich people would do for fun, like James Cameron going to the Mariana Trench.

edit: I appreciate all the responses, and while you all explained like I'm five, you weren't rude and that's appreciated

If' Elon Musk has taught you nothing else, it's that getting to space is really, really hard and expensive. Getting a submersible that can withstand the depths of the ocean is small potatoes in comparison. Least of all that you're not sittin on top of a giant bomb that can go off if something goes wrong. The worst that can happen is that you spring a leak and are crushed like cotton candy in a fat kids fingers.
