It sounds to me like universities should just stop wasting space in the library on study areas, and downsize the library a lot so it only has rooms for books and nothing else.

Then, they should separately have buildings (or separate spaces within that building maybe, for existing structures) that are dedicated entirely to studying, with both quiet areas with cubicles (there were things like this at the library when I went to college), and more open areas where talking is acceptable. Then, the university can put a cafe there to sell overpriced coffee drinks and snacks, and the building should be very profitable.
