To rule is to create a system. A system is by nature inflexible. Any flexibility it exhibits should be of a preconcieved nature, because the value of a system is in its reliability.
It must suit its participants. The less it suits its participants, the more enforcement cost will be imposed upon the system, and the less effective it will be.
It should be minimal in scope. A system should exist to protect specific needs in a reliable fashion.
In an ideal system, any person should be able to fill any role, and every person should be exposed to each of them.
Adhering to such ideals in designing systems ensures that every person understands intimately how the needs of their life are met, and cannot argue for change or discontinuation from a position of ignorance.
It also ensures that the needs that the system are fulfilling are met in a resilient fashion.
The system should not be able to lose coherency because of the loss of any person. People are too dynamic and transient in their nature to be depended upon as individuals within a design.
No person should have such heavy responsibilities laid upon them as would be imposed if it were designed otherwise.
No reasonable person should live in a system where their needs rely on the continuing competency and goodwill of an individual without making efforts to escape that situation.
