If males like Tiffany tell a doctor they've been using women's toilets for 2 years and have got the sex marker on their documents changed and have gone off on one at the utilities company for addressing the bill to "Mr" they can easily become "legally female".
When "legally female" they are considered by our next government to be the same as women, but with more legal protections. Many in our next government view having to talk to a doctor as "degrading", so would do away with that part.
Whether or not Tiffany is wearing lipstick and a skirt or has had some fake tits implanted on his chest is neither here nor there. He remains a male bodied human socialised male in a patriarchal society where male violence against women and girls is endemic (rape being virtually legal); maternity discrimination is rife; and the gender pay gap persists.
