It hasn't suddenly begun in 2024, and institutions have lasted those hundreds of years, while being under constant assault by one mindlessly ambitious resourceful group after another.

Blindly pick any institution you want, and go look at their history. In fact, most would have been set up in reaction to some groups delusional activities. Its hard to find a single institution that some group hasn't tried to shutdown, control or exploit.

Institutions survive for the simple reason, that these groups don't have solutions for everything that happens in a complex ever changing universe.

And sooner or later the universe will throw some complex problem in their lap, that breaks whatever mental model of reality, their 3 inch chimp brain can hold. Such people and groups come and go all the time.
