As we become purer channels for God's light we develop an appetite for the sweetness that is possible in this world. A miracle worker is not geared toward fighting the world that is but toward creating the world that could be.
I am still a victim of chess. It has all the beauty of art - and much more. It cannot be commercialized. Chess is much purer than art in its social position.
Of course art world ethics are important. But museums are no purer than any other institution or business. Academics aren't necessarily more high-minded than gallerists.
