You're assuming that we can distinguish between map and territory and science is definitively proving we cannot. See Dr. Robert Sapolsky on behavior as an example.[1] And philosophers like Kant speculate it's map all the way down, so to speak. That perspective is very compatible with everything we know about the world and ourselves. You'll need extraordinary evidence to prove you have a handle on what territory is. Because at this juncture pointing to anything as territory is an extraordinary claim. And sure, instead of legal classifications, one can discuss ethics related examples. Such as what makes for the good life? Something as simple as saying, the good life is based on some common sense notion of good or the good life is different for everyone and dependent on unique personal circumstances, already assigns numerous categories implicitly. That doesn't mean that both of those notions of the good life cannot be right. It does mean that we need categories to discuss and reconcile their differences, if we wish to have a pluralistic and liberal [in the 19th century sense of the word] society.
