Why would you live off campus?

Why do people live off campus I don't get it. The dorms, or at least my dorm, is nice asf and cheap asf for DC. Its right next to my classes, and has a whole staff to clean and maintain the building. I just don't see anybody saving more than like 100 dollars a month and even if they do manage to do that, their room is going to be SIGNIFICANTLY lower in quality. I'm only a freshmen though, so please do enlighten me.
