> The difference is that some things get hammered into a Constitution and are indisputable without a significant process.

Yes, but there's an alternative 'significant process' which is to simply have a political party capture the body which interprets the constitution, and then an elite group of powerful insiders captures the political party, and then you're just an oligopoly but with additional steps.

Definitely. But, for what it's worth, that's a process that takes decades and requires an electorate profoundly asleep at the wheel. Like one that fumbles an election during a pivotal year that decides the timbre of their judicial system for a generation.

Certainly not impossible though.
