It's because most people are trained by consumerism to think of anything with a human touch as flawed. The artist Tom Sachs talks a lot about this in his work. He can't make any of his art as perfect as an iPhone, but on the flipside, Apple can't make an iPhone as imperfect as any of his art (fingerprints, spray paint, a crack, etc.). I think it's important now, more than ever, to protect our imperfect things--they tell us that humans have been involved. Spirit is far more important than perfection, the former makes us smile while the latter makes us anxious.
