I wasn't so certain. It took me about 6-8 months to decide to transition. I think the way to do this would be more to make therapy easier to get and not harder. It was very easy for me to get into therapy and that made it really likely I would do it. It was also easy to go to support groups in that they were available and a couple days of the week. So there were options.
It isn't the same as saying that some people would have informed consent and some would not, but that the option of therapy is easy to do so that a lot of people would say I want that, since it isn't hard to do. I have a friend who lives in a different area. She has had a harder time and had to go thru a gatekeeper who misgendered her and this sort of thing which was aversive.
