That makes me wonder, is the pseudoscience that has infiltrated our central authority the inevitable result of a weak point, or merely someone fooling all of the people some of the time?

A concentrated community of Right-wing libertarians/Anarcho-capitalists are destined to destroy themselves if they attain any sort of power, as they follow the Ayn Rand school of selfishness to the extreme. Grafton, NH isn't far off from how Bioshock explored the same ideas and how it would lead to societal collapse.

left wing libertarainism/Anarchism, on the other hand, is mainly collectivist, and we have well documented examples of that political theory working extremely well when put into practice.

1936 Catalonia during the Spanish Civil War organized an Anarchist society with over 3 million participants, and they documented much of how exactly they ran it, right down to how they kept the electric trams for public transport going (there is a fantastic book embedded at the bottom of that article, Collectives in the Spanish Revolution by Gaston Leval, which offers more details on other aspects of how they operated that society).

It's a fantastic historical event we can learn from and build upon.

Libertarians aren't the brightest bunch to begin with, but regardless, saying "look at this community that was wrong" in response to people wanting to remove central authority is not really an argument against the idea.

The entire point is that people are free to govern themselves. Governing well is up to the local communities. Some would do better than others, certainly. But with time, people would discover what works and what doesn't. They would make mistakes like these and learn from the natural consequences of their actions. It's imperfect because humans are imperfect.

Next problem in the world right now: trash dumping.

climate change that the Army defends and creates directly

Fuck reality.
