Seriously, universities before WWII spent a lot of time trying to “morally improve” their students. For example preventing male and female interaction unless under faculty chaperone, forbidding students from owning cars, and requiring students to live on campus and to be in their dorm by a particular time, with curfew. In many schools, undergraduates could not even marry.
The returning WWII vets put an end to that totalitarianism, and so schools were much freer places for a long time.
However, the impulse to control students’ lives is a strong one. At least before it was in the spirit of ‘Alma Mater’ (Caring Mother), but now it is a cross between the “control issues” of the administration and faculty, and crude leftist indoctrination.
Soon, the students will rebel by taking their social lives off campus. And the schools will retaliate (some already have), by decreeing that even off campus activities can be controlled by them. Eventually they will get back to trying to make campuses “minimum security educational experiences”, by forbidding students from leaving campus without permission.
It's not the making of rules that is the issue, it is the current PC nature of the rules that is the problem.
