If we unbundle the courses and/or make MOOCS minimally OK - what's to stop students hiring their own TA to help them through. So long as you pair this up with a nationally recognised micro-credential framework you could see the development of a "faculty" led small-school revival. Add in some sort of matchmaker service at critical mass, some sort of pedagogy credential (how to teach well, not what to teach) and education becomes a nice small business opportunity for PhD holders.
