The clubs usually enforce no filming of performances pretty well. I want to know that what I'm doing is in the here and now and it's mine. I absolutely want control over my performances. And it is actually scary to see someone filming you without permission. Like Big Brother is watching. All these cameras don't make up for a life that isn't well-lived! I agree that people don't live in the moment, they instead live to make a name for themselves as "people who are living exciting lives and at great events".
