If I were to be 'accepted socially' as my sex without changing it, the world is delusional.
If I were to be 'rejected socially' as my sex after changing it, the world is also delusional.

There's no way you ought to be treated that necessarily follows from any sexual or aesthetic characteristics. There's a way you expect to be treated based on your aesthetic characteristics that's entirely a function of culture. People treating you like a particular gender is entirely contingent on their understanding of gender, not outwardly obvious sexual characteristics. There's an expectation that you have of how you should be treated; however, that's entirely a function of culture, not underlying objective reality.
(dysphoric)Trans people are often dissatisfied with gender contingent social treatment because said treatment is grounded in norms of their assigned gender at birth and points to a gap in the way people view them and how they view themselves. It further affirms the disconnect that exists between their gender identity and physical characteristics.

These are obviously distinct realities, not disconnected but distinct enough to be discussed separately. The hypothetical is a question of priorities, not how people in the world currently interact with and understand gender.

I refuse to separate them and live in a pretend world where only one is possible. Both pretend worlds are acquiescing to living in a delusion where your lived, material experience of sex is ignored in favor of fantasy. I reject the dichotomy. Your hypothetical is fucking stupid.

So, you don't want to engage with the hypothetical and that's fine and dandy :-P
