Sovereign,
You're not offering proof, or even a theory about the moon landing being faked. You're offering a possible motive in the event that it could be proven or theorized that it WAS faked. Fair enough, and I agree with your reasoning. But motive alone doesn't offer any sort of proof.

Hillary Clinton had a hell of a lot of motive to go Lorena Bobbit on Bill Clinton. But that's hardly 'proof' that our 42nd president in fact has a surgically reattached willy.

As for the 'why don't we still go there' question, one simple answer. $$$$. It costs a lot of money to go the moon, and as far as I know, there's almost no return on the investment. Scientists would love to go back and make some more experiments. But until there's a compelling reason to put that kind of cash into it, there's no reason to do so. Somebody who DOES have a reason to do so, namely to prove that they too can do it, is in the process of doing it now and should land around 2008: China.

Trust me, find some uranium or oil reserves up there and you'll see just how plausible it is.
