Is Scrum all about anarchy? Well, yes and no.
Yes, because Scrum is not about forcing rules and creating enforcers of this rules. There's no hierarchy and authority representatives, no one is entitled in a controlling role.
One common misunderstanding is believing that the Scrum Master is like a police officer that has to make team member follow the rules of the "true Scrum".
No, because Scrum has values and principles that one should understand and follow. Working agreements reach consensus in the team and are applied on discretion. The team auto manages itself and decides what to do and how to do it.
Scrum is all about negotiation, inspection and adaption. No imposing something and making it work by force.
