While the idea — of shuffling a societal system a little bit to prevent it from going stale — sounds important, I'm not convinced. Random shuffling leads to good results only when it is combined with a good fitness estimate (see: natural selection). And establishing a fitness test for a societal order seems to be a much harder issue than than that of an organized randomization.
Speaking of random shuffling, I think it should be made much easier to conduct RCTs on citizens to try out systems of governance/social programs/etc. to see what works best.
Basically test stuff instead of guessing and voting.
I think citizens are equal enough if they have equal chance to get to the treatment group.
