Yes. We did. There's rocks on the moon. That's it. We went collect moon rocks several times. We put a flag there, we put reflectors up there. The moon itself is rather boring. Saying your question is "good faith" doesn't necessarily make it so. Same with implying you have a "steelman" argument. It's not. It's an idle thought. The only reason to go back at this point is to conduct certain types of research. The moon doesn't have the same protections as Earth with regards to radiation. You can't just chuck some people and some plants on the surface and call it a day. But it would be a good place to see what could withstand the radiation. Ways to mitigate that radiation. Ways to field test certain extraterrestrial bases with the least amount of risk possible. I mean, it's still 240k miles away, so if something goes really wrong, you're likely dead. But it's not like you're halfway to Mars and you realize you forgot to bring water.
