I can't help but wonder why the humans in this story did not simply say "We long ago invented chemical means for individual humans to achieve perfect, undifferentiated happiness, but most individuals seem to consider themselves happier without their constant usage." This is perfectly true, and, if it perhaps would not have completely satisfied the Super-Happies (no doubt they would want immature humans anesthetized until they were old enough to choose) it might at least have served as a significant piece of evidence. I can hardly imagine a society that has legalized rape retaining a taboo against the use of Ecstasy or some future derivative thereof.
