I would beg to disagree: "The DSM is a bunch of nonsense. As long as [...], it’s worthless."

And when does the DSM ever provide the "underlying physical process"? It certainly doesn't for ADHD or any other chapters I happen to have read, which would make them worthless according to your criteria despite overwhelming evidence to the contrary.
And while I haven't read all 1000 pages of the DSM because it's not exactly my idea of a good time, I don't think it provides that kind of information in any chapter because we simply don't understand these disorders to that extent, as your original comment correctly observed.
