You gotta love the implied premise that there's a problem to be solved, because of course that's all our government is good for: solving problems it creates.
I think the problem here is the government's tendency to lie to its citizens. The solution is unrelated to aliens.
I think one of the most effective strategies of conspiracy theory content relates to exactly this point. You bypass the examination of evidence, and entertain theories that would take evidence as given. I remember a video my stepdad saw about Aliens On The Moon, supposedly there to harvest H3, that, instead of asking whether it was true, asked "what do they want?", and "what are they intending to do?" And there was a part about a grainy picture of the moon, with a narrator suggesting looked like there was a cannon-style weapon, asserting that "experts believe" it is aimed at Earth, implying that it's to keep Earth from challenging them for the precious H3.
Just like that, you are pulled into a story, with all kinds of psychological threads. You run before you're able to walk, essentially, and you get people caught up running, and you can backdoor the presumption that the underlying premise was indeed established.
So, I completely agree at there's such a peculiar note being struck by this implied premise.
