Obviously the flat earth narrative is some kind of badly designed koan intended to create a new perspective on things. The problem is that it is based on a lie, unlike koans which are based on reality like "The sound of one hand clapping."

A much better koan is something like "Plants are trying to kill you" or "Nuclear bombs are a hoax" or "The Government is here to help you." There has to be some truth to reset the narrative in our head to produce the aha moment.
