My goodness, if a woman would write about men that way, the Buddhist world would be on fire. 
I can’t believe the Buddha instrumentalized women by defining them to be useful - or not. If we’d read “But, young women, what use is a man to you?”, that would sound pretty disrespectful to men. We don’t use eachother, right? At least, that’s not how I see relationships with men and women. I’m quite surprised about this intrinsic mysogenistic way of writing. I believe the Buddha did have a more respectful way of relating to women.
