The essay [1] from which the hairdryer anecdote is quoted has the thesis that categories (in general) are instrumental, and don't have much value separated from their context.
ADHD is a category of psychiatric diagnosis; psychiatric diagnoses exist to address deficiencies in function.

If one happens to have some of the traits of ADHD but it doesn't affect their life negatively, so what?
