Oh hey man,we live in a patriarchal society for a reason. If it didnt make sense,as you say,patriarchy wouldnt be so important. We would why not follow a matriarchal system? But also,like lunatic said,half of the population (half of the population thats physically superior,basically the strength of society,the base of infrastructure and all) ceased to exist,the world wouldnt be all tulips and roses.
