Distributed dispute resolution services, a market for justice, as the foundation for a society free from most of the issues that plague the stationary-bandit state characterized by attempted monopolies on violence, law, and coercion. A system that lasted many times longer than the US did as a free society before falling to cartelization.
Everybody kept the social peace, because the cost of breaking it was too high: nowhere to go to escape societal retribution, everyone "knew" everyone else or could pick you out as a stranger in the local community if you moved around the island and would get your back-story eventually.
Democracy biggest success, despite its significant imperfections, is the orderly overthrow of government every 4-5 years. Even monarchy doesn't guarantee an orderly transition of power.
Not only that, the larger it gets, the smaller the proportion of what gets replaced at every election. Even if we get some new Congressmen every two years, we still have all the same spies, SWAT teams, prosecutors, defense contractors, etc. And the things with staying power throw money at perpetuating their own existence, so that the Congressman dedicated to halting the proliferation of SWAT teams or reducing the defense budget doesn't stay a Congressman long enough to attain the committee assignments that would allow him to actually do it.

I'm struggling to think of many examples from the history of the UK/England/Scotland (and there was a civil war 350 years ago to end absolute power of the monarchy), were there saner royals elsewhere in Europe before everyone switched to keeping their royals as fairly powerless heads of state?
The Queen of the commonwealth for example and shut down the parliament if she wants to (there is a complex process to do it, but it can be legally done), or buy and sell state stuff freely. Of course, in information age, she knows that if she abuses these powers, people will get upset and overthrow her.
Also in Japan, the monarch legally has no power, but the people obey him anyway, this happened many times in Japan history, and seemly the population like it that way because the monarch become a "failsafe" of sorts, every time some non-monarch leader do major shit, the population can rally behind the emperor again and return his absolute powers (and usually subsequent emperors fix the issues, until someone pull a WWII...)
There's an interesting EconTalk discussing the Ancient Greek economy where Russ Roberts asks his guest: "We certainly romanticize Greece as this great democracy; but it wasn't much like the United States, tell us about it"
But after Josiah Ober describes Athenian democracy it ends up sounding like what we call modern democracy is a very poor imitation.

I think people are turned off by the idea of some random "crazy" running things, but that's exactly what I think would provide checks and balances to a government (namely, that the "crazies" don't reach a consensus as easily as the corrupt).
And on another level, our laws would have to be understandable! What would that be like? Would I actually know why I am being arrested?
Moldbug comments that people who use this quote rarely give serious consideration to any of the others. Universal democracies are a very new form of government, and to ignore their problems requires willful ignorance.
At least - a system without elections doesn't breed people, whose primary ability is to get elected.
There's that famous phrase (Churchill): 'It has been said that democracy is the worst form of government except all the others that have been tried'. But this is more subtle: it's about lying, and ultimately, corruption. Is this a solved problem in hard political science?
I know of various solutions explored in science fiction, notably by Robert Heinlein, Arthur Clarke, Eric Frank Russell, Christopher Anvil, et al. There's game theory, where cooperation 'breeds' more cooperation, in a world of defectors.
But, it seems to me, corruption is now the biggest problem facing humanity. If we can fix that, it'll cascade down through everything else: climate change, energy sources, ecological destruction, sexism, etc...
