To try to answer you anyway, they've put a fair bit of engineering effort into making YT mildly painful to use without Premium -- things like not allowing sound to play when the screen is off (and covering your screen in ads for Premium if you wake up the phone to a running YT instance). I'm sure some people pay for Premium to improve that experience.
