The fine art/commercial art dividing line is problematic for the reasons Travis has stated. What touches good often has little to do with whether someone was paid for doing it or not. The Ateliers of well-known artists have always been commercial ventures with the goal of making a living.
Money is not evil, it is the love of money that is the problem. Money fairly exchanged represents value for one's life spent doing what has been sold. I respect money earned. I think the distinction that might be a better one is vocational vs. liberal art. One done in the service of a customer, one done in the service of the idea, but both using the same means and both sharing the potential to be grand expressions of the human spirit.
