Probably needs to be 8pm so they can get home from work - except for key workers. But yeah, sounds like a good and necessary thing! A great idea. Male violence is the issue.
Hmm. So you will have a list of key workers. Doctors, nurses, carers, maintenance engineers, electricians, gas workers, ambulance drivers, paramedics, firemen, emergency response co-ordinators, water mains repairmen. Then you have refuse collectors, delivery drivers, HGV drivers, factory workers, power station workers, miners, bar staff, door security, cinema and theatre workers. Oh, and police, obviously. You will have safer streets, and nowhere to go.
Who would actually qualify for quarantine? Accountants, marketing tossers and teachers. This can't be a one-off thing. What you really need for it to work is a segregated society. I don't blame you for feeling that way, but I don't see how else it can work. You need women to run every aspect of society.
