I think the lawyers in a straw-man imaginary world where they say a university can't e-mail any FERPA-covered data to a student (which includes such basic things as what times a student's classes are) don't contribute anything to society. But that's because they're just a figment of one person's imagination.
Actual, real lawyers who work for or at real universities often do contribute quite a bit of valuable work. I enjoyed the one I worked with and think she did a great job of putting the brakes on over-regulating or using legal compliance as an excuse for just not doing work.
