Secret backstory: FSM is a designer at Universal Studios, and was shouted down when he said snowcapped roofs in the middle of Florida and a tenth-scale Hogwards with a warehouse sticking out of it would be unimmersive/cheesy and proposed "Lampgreen," an American equivalent to Diagon Alley, and is now unleashing sour grapes at us all because Disney elected to use his supposedly unworkable concept for Star Wars Land.
(Alternatively, secret epilogue: The "Fantastic Beasts" movies unfuck themselves, and in an act of perverse revenge, I, now a designer at Universal Studios, lead the expansion of Wizarding World to include an original American wizard-town, which I name Lampgreen.)
