How is this different than making the argument about online universities in general. Why pay for sports, why have gyms, why have food service, etc. I used the library whenever I did research for papers, and not all documents are available online. I feel like you rather than making a critique about libraries specifically your real argument is about the utility of services a college provides and need for said services. IMO, this argument is a fast track to privatization and gatekeeping what otherwise would be considered a public asset.
