Why are college students ever trusted to run their own lives?

I'm reading "Expecting Students to Play It Safe if Colleges Reopen Is a Fantasy/Safety plans border on delusional and could lead to outbreaks of Covid-19 among students, faculty and staff" by Laurence Steinberg (a psychology professor who wrote a book called "Age of Opportunity: Lessons From the New Science of Adolescence').

Most types of risky behavior — reckless driving, criminal activity, fighting, unsafe sex and binge drinking, to name just a few — peak during the late teens and early 20s.... Under calm conditions, college-age individuals can control their impulses as well as their elders, but when they are emotionally aroused, they evince the poor self-control of teenagers.... But it’s hard to think of an age during which risky behavior is more common and harder to deter than between 18 and 24....

My pessimistic prediction is that the college and university reopening strategies under consideration will work for a few weeks before their effectiveness fizzles out. By then, many students will have become cavalier about wearing masks and sanitizing their hands. They will ignore social distancing guidelines when they want to hug old friends they run into on the way to class. They will venture out of their “families” and begin partying in their hallways with classmates from other clusters, and soon after, with those who live on other floors, in other dorms, or off campus. They will get drunk and hang out and hook up with people they don’t know well. And infections on campus — not only among students, but among the adults who come into contact with them — will begin to increase....

[U]niversities must be informed by what developmental science has taught us about how adolescents and young adults think. As someone who is well-versed in this literature, I will ask to teach remotely for the time being.

We need to keep these little monsters locked up until they're 25. Who knows what they will do with their freedom? They might party in their hallways and become cavalier about wearing masks and sanitizing their hands. There's no end to the dangers of freedom. You really cannot trust people to put safety first, week after week, month after month. At some point, they will hang out and hook up.
