In agrarian societies women often worked with their husbands running businesses from home, or did farm labor.
The idea of women being useless beyond childrearing and cooking or light housework is nothing more than a monstrosity of the late 19th and early-to-mid 20th century middle class.
Women of the aristocracy for centuries back didn't even care for their own children, usually, and never cooked since they hired people to do that. They were educated to read, write, paint, play music, dance, et al. even though they did not work.
We're not going to go back to "the stone age" because we aren't Neanderthals anymore, and I believe we've genetically evolved past that point, not just socially. It's absurd to say that humans are reduced to this simplistic roles because we have advanced cerebral development.
Jesus fuck what is wrong with you people.
