I think those rules are a good thing. My campus recently started to allow 24 hour visitation on the weekends. I never could live in the dorms because of all the coming and going. The visitation policy was never really enforced unless there was a overzealous RA. I don't know how people could get any work done in those environments. The campus recentlly introduced Leadership dorms and academic dorms where the noise level would be lower.
But that aside, 18 year olds in college for the first time can make immature decisions, especially since many are away from their parents for the first time.
As for sorority houses, the rules are there for a reason. Although they are a a throw back from "the old days" The rules decrease the sororities liablity. Also Do you really want to have a guy in the bed rooms when people are trying to sleep, ect. This rule limits roommates ablility to be inconsiderate to each other. I have heard of girls that practically live in their boyfriend's fraternity house, (yuck) so I imagine that the reverse could happen without the rules being in place.
