I think you are being unfairly downvoted. Campuses have the ability to do things like expel their residents and physically remove trespassers, which is only possible in the most draconian gated communities in the “real world.” They filter for things like SES and at least a nominal desire to learn. They can shunt the really hard problems, and problematic people, to the rest of society.

there is also a filtering process just to get there, both with the military and college. even more so when you filter by military officer or grad student housing.
