I think the flat hierarchy in the Scrum religion is an oversight. When designing a religion, what you generally want is a sense of accomplishment as you climb the ladder towards alumni status, with knowledge revealed in rituals such as commercial lectures and materials along the way. This is what gives people a sense of achievement, keeps people stick to a religion, and makes a decision to drop out increasingly hard. L. Ron Hubbard did know about this aspect of human nature all too well.
