Yes. For me tg stories are much more compelling if they can actually (almost) happen in reality, and hypnosis of the kind usually seen in tg fiction is not realistic. Realistic tg stories aren't impossible to write and everyone seems to like them (e.g. the Blondie series), so hypnosis just seems unnecessary to me.
Also one of the aspects of these stories I enjoy most is descriptions of the thoughts/feelings of the protagonist as they're being tricked or forced into being feminized, which you don't really get with hypnosis stories.
The best you can hope for is in something like Ruined by Resolutions, which is just a lot of "Omg, why am I putting on a dress?", which I don't find that interesting.
