This isn't Schrodinger's cat, a lack of observation doesn't make the chromosomes go away, and really focusing on intersex people when the topic is trans people feels like a bit of a shell game anyway. You are however entitled to your opinion, to present as you see fit, and I think you have the right to be treated according to how you present.
When it comes to the law though, word games are unhelpful and get in the way, clear definitions are required. In terms of respecting human dignity, these definitions change nothing; people inclined to respect trans people will still feel the same way, and bigots will hardly change either. You can still have laws and legal structures designed to protect people while recognizing the reality of their biology, because it's about GENDER identity, not BIOLOGICAL identity.
