In an autarchist republic, no one has power over anyone else. All power is voluntarily granted and can be withdrawn at any time. So, I don’t think the same incentive structure towards corruption exists. It is the socialist-ethic which says that majority-rule should override individuals wills on X issue that allows corruption for it allows the aggression of majority rule to force laws on the majority dissenters.
I like that analogy 
awful.
It’s hard to come here and argue for autarchy and be accused of being a statist. I hate the modern abuses of the state as much as anyone. But I think there’s another way that might redeem the state. A way that we haven’t seen before essentially because for autarchy to exist in a practical form we require modern technology such as computers, the internet, and geolocation systems.
In a world without the internet, the only way to rule a massive society was via representation. Which meant the socialist-ethic of majority rule was ingrained in society as the only viable system. An autarchic society can reject majority-rule because we no longer need representatives like we used to. Distance and time mean almost nothing to a modern person.
