A core tension within the alien "Disclosure" narrative

Steven Greer, one of the most prominent Disclosurists, claims that the US government and private military contractors are in possession of alien technology that could usher in an age of free energy and thereby a profound social, political and economic transformation for humanity, and that the truth about this tech is being concealed for this reason (so that Big Oil, the military industrial complex etc. can maintain control and continue to rake in profits, etc.). This would imply that the aliens themselves are peaceful and have superseded their own social and political problems and have achieved a more morally advanced society than we have, since they are advanced enough to not only have that technology but to use it to visit other star systems. 

But Greer also claims that the inventions of people going back a century or more have been suppressed because these inventions offer free energy. The inclusion of the alien myth seems rather redundant here, but it also evinces a tension in his narrative: why the strong emphasis on alien tech and saying that UFOs are ETs with technology that can save our planet and civilization from ourselves (this is part of the broader Celestial Savior appeal of the ET belief system, in which aliens are seen as saviors and redeemers, much as God has been seen in such terms for millennia) if humans are fully capable of figuring out this tech themselves? And why would alien tech save us if we can't save ourselves by implementing our own inventions and reforming our social relations? Surely, to truly evolve ethically, we would have to figure this stuff out on our own rather than waiting for an Ex Machina of super technology bestowed to us from on high? A lot of the UFO mythos centers around the notion that aliens are keeping up as arm's length because we're too warlike, aggressive, irresponsible etc. to be allowed into their galactic federation just yet. But doesn't the expectation of "this is going to fix everything" itself betray a certain irresponsible and infantile mindset where we take a shortcut to salvation, kind of like a student who doesn't want to put in the work and just asks AI to write him/her a report?

The ETI (extraterrestrial intelligence) myth (the term used by theologian Ted Peters) is at core really a religious/theological one with eschatological and shamanic overtones but that represents a type of scientized or secular theology involving physical beings and technology. Peters describes it as a "gnostic redeemer" account, in which knowledge (in this case, scientific and technological knowledge) saves. If only we could get our hands on that technology, we could fix all our problems and become better. Indeed, many depictions of alien civilizations in the UFO milieu (certainly within the subgenre of the Contactee stories from the 1950s onward) portray them as not just more technologically advanced, but more morally and spiritually advanced. The focus these days (since the end of the Cold War, where the nuclear threat was the predominant social/political backdrop in people's minds) has been the threat to ecology and environmental sustainability. Hence the hankering for free energy to power our civilization and allow us to ascend to the heavens, perhaps ready to join our Space Brothers in the celestial Promised Land.
