I think you picked an example where he's wrong, but not completely wrong. I agree "shell shock" wouldn't suffice but you could just change his word to "past-shock" or something, and notice how different that feels than an 8-syllable medical phrase. I do think putting big fancy words on things implies a fake level of understanding, takes the word away from everyday users, and has other real effects.
