I like that this is trying to put cisgendered people into the role of transgendered people, and to give some people some insight into what it's like to be consistently misrepresented and judged. On the other hand... you missed two things. One is that the pressure for the body to conform to the mind doesn't suit everyone. While some people are obviously better off having sex correction surgery, others only suffer due to the expectation from heteronormative society to look like this or that, and from other trans people to be a 'typical trans person' otherwise you're not 'real'. It can invalidate a person as much as pronoun misuse etc.
My other problem is that this is very gender-binary. A 'No' option at the start would be pretty good... I know some trans people like to think that genderqueer individuals are attention seeking or fake though. It's funny to see trans people say the same stuff about genderqueer people as cis people do about trans people. But I assume it's just an oversight in your case.
