It gets us a concept to refer to the set of adult human females. (Even if, again, we often also use the word _woman_ in a broader trans-inclusive sense; it's not uncommon for words to have both narrower and broader definitions which can be distinguished from context.)
-If the concept of _women_ in the narrow, trans-exclusionary sense is to be forbidden from polite Society, then people trying to make sense of the experiences will be forced to reinvent it, probably by means of obfuscatory neologisms ("assigned female at birth") coupled with the indefatigable [wordless anticipation](https://www.lesswrong.com/posts/a7n8GdKiAZRX86T5A/making-beliefs-pay-rent-in-anticipated-experiences) that it's _somehow not a coincidence_ that cis women and trans men get pregnant sometimes, but cis men and trans women never do.

I _want_ to live in that glorious future of Total Morphological Freedom. But _nature to be commanded must be obeyed_: to _get_ godlike mastery over our physical forms, to _break free_ of the prison of today's unremediated genderspace, is going to require a detailed understanding of exactly how things work _today_, as such knowledge is the only thing that can inform the design of a superior solution. And the fact that _the smartest people I know_ tend to direct more of their effort towards redefining top-20 nouns than on biotechnology research, does not exactly inspire hope.
