To avoid being needlessly confrontational, I will also note that the comment you quoted was in response to the claim that NASA hasn't done anything with their trillions, so I listed a bunch of things, none of which have anything to do with manned moon travel. There is NO REASON to go to the moon unless you're completing a vanity project (which there is no real point in repeating), or are establishing a base of some sort there. There is no good reason to establish a base there currently, since low earth orbit works much, much better if you want a base to serve as a "launchpad". I could see them wanting to put a base on the moon as practice for a Mars habitat, assuming they ever get that far, but I don't see it happening anytime soon.
Note I haven't said anything about Van Allen belts. As I said, there are reasonable arguments to be made (and that's one of them). I disagree with you, but if you want to make that argument at least you have a leg to stand on.
