In fact I think that Judaism and most of the free world would collapse without them. The reason women do not need as many ACs as men is that there are so many natural constructs available to them. Their role in G-d's world is predefined by their bodies. They give birth, suckle children, menstruate, and their derivitives of nurturer, pleasure giver, safe haven, creator. Their bodies tell them what their role or potential role is.
Men only have one role defined by their bodies and it is a rather transitory one.
Thus, artificial constructs are needed to give the male a role in society so he won't be destructive to society. In her study Sex in Three Primitive Societies, she shows how the roles of men and women in each of the societies are reversed. Men are often catty, walk with a mincing step and go to market to collect the groceries while the women hunt or work the fields. She noted that in each of the societies, whatever role the male had, it was considered by their society as the most important work of the society. I do not object to women driving trucks, leading prayer services or becoming rabbis.
