Over-furnished dorms: Why? Why?

Typical dorm setup. Standard equipment everywhere.

What your real issue is the size of the single. I just looked up my D’s former college, and a standard single was 96 sq.ft., with a double at 192. Of course, the latter has 2x of everything on your list. But the rooms still had space to rent/bring a micro fridge.

Welcome to life as a Frosh. Some colleges, like UCLA, have forced triples for Frosh, i.e., three students in a 2-person, or 192/3 = 64 sq.ft.per person. Somehow, UCLA still receives 100,000 applications each year.
