Because anarchy in the patriarchy would actually be worse for women, in my view. Peek into a dudebro's mind to find out what he thinks "anarchy" would be like, and you'll see a nasty rapey world, all Mad Max and Thunderdome. Eff that. I'll take the U S Constitution over anarchy as long as I live in a rape culture, thankyouverymuch.
Am I a socialist? Kindasorta. Same problem applies: the same minority of white hetero able-bodied old white guys will still be decided who needs what, and who needs to give what. Guess who'll stay at the bottom of the food chain? Yeah, before revolution, chop wood carry water, after the revolution, chop wood carry water. On the plus side, the massive inequities in wealth would be eradicated and a lot more people would have an education, health care, a clean environment, and at least a decent shot at living the life they want to live. You can take the boy out of the government but you can't take the patriarchy out of the boy.
