As a thought experiment, imagine a world where borders exist as they are but the whole political process inside them everywhere is to 1) choose a zone randomly 2) choose a citizen randomly 3) receive policy proposal from them 4) vote yes/no on policy using random dice 5) for resolving ambiguity on any and all policy details such as "how much" or "for how long", return to step 1.
It's uh, king for a day, with checks and balances on human cruelty via chaotic caprice. How likely is that world to be worse than ours? If so, how much worse? If not here and now, then which counterfactual geography or year would you have to transported to so that this randomized process is definitely preferable?
Here is the problem: what if it is worse in ways that none of us can think of today? How do we get out of this system if it turns out bad.
History has shown everything we have tried ends up worse than what we have, but that doesn't mean there are not things that could be better. Only that we need to be really careful not to make things worse in a way we can't get out of in our attempt.
