The thing is, Guest mg, most of the women would flatly refuse to be controlled like that. (Advantageous though it would be!) Unless they were totally 'enclosed' as in a prison, they would be having unprotected sex, getting pregnant, taking drugs and all the rest. One cannot in all conscience forcibly control every aspect of their lives. All that you suggest is excellent, but I still don't see how it could be implemented. As having illegitimate children is not a crime, one cannot 'punish' them. And withdrawing benefits would only increase their criminal activity. (Actually, no youngster on benefits can possibly live on the tiny amount it offers. They all do things to augment it.)
