CA, ok, it’s an interesting point that you are making regarding women having lower spiritual end points but you don’t quote a source so until I see a source I’ll take it as your opinion.
In any case, I don’t think a woman being a nevuah is such a low spiritual point… And people’s highest spiritual point is set high enough for both men and women – our spiritual potential is immensely great and not in any way “low” for women as you claim it is. I’d be overjoyed if I reach my spiritual potential at 120, even if I don’t end up being a tzaddik gemor…as will most men be happy to reach their potential even if most of them WOULD NOT end up tzakkikim gemirim even if they would fulfill their spiritual potential.
As Reb Zusya of Hanipoli said he will be asked in the next world why he’s did not rise to the level of Rav Zusya, not why he wasn’t a Moshe Rabbeinu.
So as far as I’m concerned, we each have our own spiritual destiny, capabilities and potential that doesn’t hinge only on being male or female but on many other factors.
