That said we all have multiple roles with no guarantees they won't conflict. How that's resolved by an individual is their identity.

Roles are not a product of authority. It's the other way around. Taking on responsibilities is power. It's silly, but even simple household chores can be seen this way. My parents used to point out that their frustration with a dirty floor, beyond just being "my fault", also meant that I had power over their emotions and a demonstration of how we're all at the mercy of each other. Heavy stuff for an 8 year old. Sure expectations are the other side of it, but that's where bargaining comes in. They were fair to never expect me to be perfect, just good enough.
