The fact that we welcome the return of pumpkin season just masks the fact that there are no seasons. We could probably ship pumpkins from all around the world to get our pumpkin fix year-round. But even then, it's only the third order of that list above. It's not quite at that next level pure simulacra shit.
Did I mention that there's no pumpkin in your pumpkin spice latte? That delicious sip of fall you just imbibed is actually a pure simulacrum, of that fourth order. Pumpkin spice doesn't conceal the fact that there are no longer seasons, pumpkin spice has no referent in reality, it exists for its own sake. The only thing "pumpkin spice" refers to is itself.
