Organic produce was the first metaphor the came to mind: it's probably more healthy for you even if it isn't as pretty, but many people aren't willing to pay a premium it and I suspect economics isn't often the reason. Is that a straw-man for live music? I don't know that it is because plenty of people are content to listen to recorded music -- sure, they might enjoy going to a live concert but they'll still listen to the radio on the drive to work.
Then I got to thinking about something more crass: while breast implants and other cosmetic body surgery may be as much for the benefit of the subject self-image I imagine there are plenty of people that find it very attractive despite what is often obviously fake.
So do we crave authenticity? I think I do but I'm not sure if that's a safe generalization to make.
