Did the people of North Korea legitimately get an F, or were they outright conned/exploited/brainwashed by the people in power. They didn't get an F, they were given an F by a corrupt system. I mean their leader who fed his uncle to dogs gets an A I guess. Forcing A down and F up violates the non aggression principle, but if everyone opts into this voluntarily there is no force. Also it might not be A and F becomes C and C, but more like A and F becomes A- and F+, gradually over time. Just so some people can afford to eat more than their own fingernails which they can't even grow due to lack of nutrition. Centralization everywhere needs to be overthrown and such an 'averaging coin' would decentralize money and power, theoretically.
