Rule by parliament by the very way it is set up becomes a snake pit of betrayals, horse dealing and back stabbing, when alliances are made. Look into any European political discourse online and offline, and it's all about which parties should ally with which parties after the elections. A million rules are made and routinely circumvented to try to maintain a non-existent "system" of governance which isn't tied to any person, but some abstract paper construct.

Rule by strong man attracts psychopaths and narcissists for obvious reasons, and if not, at least the most ruthless people you can imagine.

>"how you structure your society"

How who structures your society? Now you're back to step one where either the psycho or the snake conspirators rule.

Any change has to first come from within. People have to personally as individuals decide to not pay taxes and decide to not follow the law when the law is unfair. These things are doable, and when enough people do it, the power starts returning to them.

Social coordination has been done for thousands of years before anybody had ever heard of the concept of "a state".

In the future - maybe in our lifetimes - the idea of a state will be irrelevant and forgotten by most. People will laugh at the idea that people revered and feared and even worshipped that paper tiger. It will collapse and disappear into obscurity just like so many other false ideologies through history. Just like the Soviet Union went from being a super power striking terror into the hearts of the world into becoming just a meeting room with a few powerless men with no country and no people to rule.
