Woman used to mean 'biological female' (a phrase you seem to be comfortable using). Hijacking the meaning of the existing word is pretty weird. You could have invented a new word to mean "everyone identifying feminine" but instead you chose to hijack the old one antagonizing a lot of people on the way. Even if successful what is going to happen is that another word is going to be invented for 'biological females', and biological females will be called that to convey that they are exactly this: biological females.
