Much if the value of art is that it links you to everyone else who views it, which is fundamentally diluted by any process that makes art faster than it can be observed. This stays true no matter how high the quality of the fast art making process climbs. Making a sculpture out of toothpicks on the other hand preserves this value by synthesizing the needed scarcity via proof of work, and would do so even if it added nothing aesthetically.
