so, don't tell me that the value of what i do is determined by how much i sell; i'll take the exact opposite position, and argue that any art that can be commodified to the point of being successful in this economy isn't worth the cost to produce it.

the only art worth bothering with in this culture is that which is permanently and inherently unmarketable.

as zappa would say, it would necessarily have "no commercial potential" to be worthwhile.
