I maintain that the mind is superordinate to the body; your woman's brain (that sounds weird but I mean this affirmingly) is what makes you a woman more than anything else. Anatomical mishaps are noise, and in the long run there is still the same signal as a cis person of the same gender. I did not mean to imply in any way that being able to pass perfectly (or even to a majority of people) was any sort of requirement or baseline.

I have no expertise or deep knowledge of gender; your comment has reminded me of the quandaries that can be involved in it. As it seems to me, the most coherent thing I can say is that gender is often a vector, and what matters most is what direction you're pointed in.
