I still had some deeper philosophical problems to resolve, though. If squiggly categories were less useful for inference, why would someone _want_ a squiggly category boundary? Someone who said, "Ah, but I assign _higher utility_ to doing it this way", had to be messing with you. Where would such a utility function come from? Intuitively, it had to be precisely _because_ squiggly boundaries were less useful for inference; the only reason you would _realistically_ want to do that would be to commit fraud, to pass off pyrite as gold by redefining the word "gold."
