This argument that is about as old as space travel itself. But just consider what the Mars rovers have achieved in the last few decades. I don't want to in any way diminish the fantastic achievements of NASA and the Mars rover programs. But the fact remains that human explorers could have done all that and much more in a couple of weeks at most. And there's a lot of things that still haven't been achieved, like drilling a hole. That would take a person a few minutes to do. All our current knowledge of Mars goes just a few centimetres deep. The really interesting stuff likely is under the surface.

As for why we should go there in the first place, the answer is resources. Lifting stuff out of earth's gravity well is very difficult and expensive. Once we manage to create rocket fuel on the moon, the entire solar system becomes far more accessible. It would also enable large scale construction in earth orbit, if we could source raw materials on the moon.

Finally, and unfortunately, there's the geostrategic dimension. Of course it would be nice to live in a world where we could all just get along but that is not how it is. Not building a presence on the moon would mean ceding it to China and you can be damn sure Dear Leader Xi would use the leverage this would provide him with.
