Right, in that case professors are surplus to requirement, all the informations in books, articles, and nowadays online. For a professor to be "good" then they need to be able to clarify concepts, in a way that is accessible. Your view of "me tutor- you student- me always right" is hugely archaic and does not lead to enthusiastic learners, instead leading to disillusioned students who drop out, or do not study further. Thank god professors like that are now are in the decline. there is a difference between mollycoddling and making a subject easier to learn.
