The problem is that the will isn't there currently, I'm sure NASA could replicate the past moon landings at a vastly cheaper rate than the originals now. With the right level of funding how hard would it be to conduct a heap of controlled landings taking things similar to ISS modules to the moon, and then use similar tech to apollo to ferry astronauts to put together a base. Given the budget is there really any tech that needs to be invented to do something like that? Astronauts could stay no longer than ISS stays so you wouldn't even need to push into new longevity of space travel. Granted the a Mars mission would be a big step up, which makes incremental improvement that seems to work best in tech progression harder. Still I think it's mostly about the budget and the will of people to want to achieve this stuff.
