Zhao's post-Edenic "fallen" worldview here is a sort of new age reappropriation of a whole bunch of religious beliefs. You could call it religion stew.
It's fine if he believes this of course--and I suppose I can see the appeal of drawing together the common threads of religions from all sorts of times, cultures and geographic regions over dogmatically following just one-- but as of yet there's no evidence for the fact that the world was once a spiritual utopia that was lost approx 10,000 years ago (although that fits in with the Gilgamesh/Eden/Atlantis myth pretty well), and much more for the fact that life was actually pretty difficult back then just like it is now.
On both extremes of the political spectrum, there seems to be a tendency to point back to a utopian past that we've lost touch with, that we desperately need to find our way back to. With conservatives, this usually takes the form of "the family", rigid gender roles, the superiority/authority of men and the natural "submission" of women to their betters, rigid top-down hierarchical structures of political power, and maintaining "pure" "racial" bloodlines. With leftists, this takes the form of a belief in a primordial past where humans existed in a deeper harmony with nature, a time before "technology" ruined our beautiful harmonic connection with the natural order, an innocent natural state where people all got along and there was no such thing as misogyny, misandry, jealousy, murder, rape, incest, when the earth was still "pure" and everyone simply danced around the maypole smoking empathogens and loving one another.
Neither of these utopian pasts existed, of course, at least not exactly as these groups wish they did.
If someone put a gun to my head and said I had to choose, I'd prefer the leftist view to the conservative. But both views, at their radical extremes, if you examine them closely, are similarly limited by an obsession with regaining a lost (and false) "authenticity", a version of "pre-mediated" nature that never existed, an idea of "natural order" that has nothing to do with biology, and ultimately, a pathological preoccupation with hygiene and purity.
