I was about to buy Jack White tickets today and... I think I'll pass. Don't get me wrong. I've seen several shows, including Jack White, that politely ask the audience to keep their phones away for part or all of the show. That's fine with me and it basically works. But as much as I'd like to see Jack White again, I really don't enjoy being treated like a child.
I don't get your response; would you not go to a state park because there's a rule against operating motorized vehicles on the hiking trails?
In your analogy, the park is doing what the commentor says. Politely asking you not to do that.
