If it were up to me, this is what it would be, and in many ways it overlaps with the transmedicalist/"truscum" view of what it is to be trans.

1. The word "gender" would stop being used altogether when referring to trans issues: we would call trans people "transsexual" and dysphoria related to biological sex, "sex dysphoria", since that is really what it is about. Only people experiencing dysphoria around their physical sex would be considered trans.

2. "Trans" would refer to people who are diagnosed by a qualified professional with physical, body-related dysphoria related to their biological sex, and who have begun physical transition. The basis for who is and is not trans would NOT be based on self-identification alone. As a compassionate person, I would personally be willing to refer to these people with the sex and pronouns they wish to be referred to with out of empathy for their condition. After undergoing full surgical intervention, trans women would be allowed legally to access sex-segregated spaces for women.

3. Gender roles and sex stereotypes would be viewed as antiquated and would no longer be enforced. No one would be expected to behave, dress, express themselves any specific way on the basis of their biological sex.

4. Consequently, non-binary identification would no longer be recognized as valid.

5. Trans people would receive protection under the law under anti-discrimination measures surrounding mental illness, not under "gender identity."
