Avira, the Gemara doesn’t mention דברי הבאי. And the proof from ״אֲנִי חׇכְמָה שָׁכַנְתִּי עׇרְמָה״, כֵּיוָן שֶׁנִּכְנְסָה חׇכְמָה בְּאָדָם — נִכְנְסָה עִמּוֹ עַרְמוּמִית implies that this applies to anyone and it’s not because of a certain biological phenomenon. However, those who are commanded to study Torah must do so regardless. And even so, as I mentioned earlier, you aren’t actually supposed to teach Halachic reasoning to non serious students.
Rashi in Shabbos describes women being at the Shabbos drashos which was geared for them as well as men who aren’t well-learned.
Another point. It isn’t fair to frame it all in terms of Tzidkus and purity. A better judgement would be about intellectual pursuit. If someone who is not really into intellectual ideas picks up some concepts here and there that would obviously be taken wrong. If a woman does fully indulge in academic studies, which is more common today than it has been, there is less reason to apply כיון שנכנסה חכמה.
This is merely an argument in that direction, but far from a conclusion. It is obviously אינה מצווה and shouldn’t be made into what it isn’t. Also, people easily fool themselves into believing that they are different when they aren’t. And, we have indeed seen the ערמה and גאות that seems to stem from the attitude of having outsmarted the Torah and Chachamim.
