Art is not standalone, it lives in a context that actually is an ecosystem. It grabs things and puts back some other things. It allows for artists to express (and, possibly, make a living out of it) and it gives back beauty, happiness, fears, objects, new uses for technology, opportunities for investments, culture, knowledge, new views on the world. Lots of stuff, sometimes including the series of orgasms that make up the addiction-inducing effects that art is starting to share with consumism in these contemporary times. Value is bi-directional and goes back and forth between all of these components.
