> [Burning Man]

I completely disagree with your impression, but that all is beside my point.

The part of the Burning Man culture I'm pointing to is the one where people go co-create all this shit anyway, when they don't have to, when it doesn't solve any need, when it's not about a contrast with somewhere else.

Not everyone needs a problem to solve to get off their arse and make something amazing, and you can see that multiple times a year around the world if you look at these events.
