Miasma used here as imagery for rhetorical effect. It really is like a toxic cloud of cultural assumptions and impositions that has choked out a lot of the folks who built the foundation of what makes Burning Man what it is, and not just some festival to wear sparkly clothes and take pictures for Instagram. Not to mention all the money that descends on the event to install shortcuts and cash grabs in an otherwise moneyless, DIY, BYOEverything space.
