I try to peal away some of the layers by supposing the "conspiracy" is "true" (for the sake of argument).
For example, (IFF) the earth is flat (THEN) who cares, why does it matter, what changes?
I mean, other than NASA being vastly more capable (of psyops) than I ever gave them proper credit for, there's really no detectable "upshot".
Perhaps, "don't charter flights directly across Antarctica"? I'm not really sure that going to "change my life".
I mean, I'm not currently an astrophysicist or an artillery commander, so...
