If I ate paint I would die. I think. Art is unnecessary for the physical survival of humans. It provides no shelter, food, or utilitarian function. Because of this, art doesn’t really show up historically until a culture is advanced enough to have free time when they don’t have to run around catching rabbits or building tree houses. After the culture has some level of civilization they can afford to spend some time on useless things like art and TV watching. So the Neanderthal first invented charcoal to draw on his cave. Then he invented Oprah.

Since art didn’t feed them they didn’t trade it for things like deer meat or roof-thatch. Instead they gave it away. It wasn’t governed by the rules of capitalism, it was governed by the Laws of the Gift. Maybe. Or maybe there was a Neanderthal Picasso who was given 40,000 ears of corn for his cubist cave paintings of deer-hunting stick figures.
It might be true that deep down we believe art should be a gift. How many art centers and libraries are provided for free public use? What about groups like MoTab that work to bring free music to the world? Art, literature, and music are often freely shared. This breaks down when the artist, musician, and writers realize that they have to survive. Art then becomes a commodity. Sometimes the price of the artwork even affects our perception of it. Is that okay? Are we losing something here? Should art be a gift or a commodity?
