If you read on, it becomes clear that most of the evidence for that article came from a handful of Facebook posts, and the fact that people were putting together guides to lay out the camp rules for thousands of new volunteers. The actual connection to Burning Man is much more interesting: Both Standing Rock and the infamous desert art festival (in its early pre-police days) are examples of temporary autonomous zones, which I will refer to as "TAZ," because even if it wasn't already an acronym, it just sounds badass.
This term, invented by anarchist philosopher and sweet-ass-name-haver Hakim Bey, refers to "temporary spaces that elude formal structures of control." Building a TAZ can be a great protest tactic. You just pick a spot where your presence can disrupt something in need of disruption and build a town around it.
There was no strict hierarchy at Standing Rock. One of the first things we saw driving into the camp was a large series of tents set up as essentially a gigantic free closet full of winter wear for all who needed it. There were also camps, and sections of camps, dedicated to providing free coffee for all.
