I hate thinking inside of tropes, it's just boring, lazy and usually wrong. When you accept the context, searching for G.E.C.K. is not that illogical. You have a dying chunk of people in tribal state who look into everything from the past as magical and mythical. So when they find a clue of something which can bring fertility back to the land they send their best and most spirited tribesman on it's search. And the G.E.C.K. then quickly gets de-romanticized into nothing but a bunch of field chemicals and collection of random seeds - another purely utilitarian item marketed in pre-war magazines as some wonder, the same magazines people now use to clean their asses with. But the protagonist, being rat-eating tribal he is, is till obsessed with it's "magic" (not very logical for someone with 200% Science of course).
The game would be better if in the end people did't actually need the G.E.C.K. to make their lives better (banal moral lesson, but at least it would still be a lesson).
