In my early 20s I got really into all those boutique political theories. Our world is big and complicated, and these marginal and fringe ideas have never been actually tested at any reasonable scale. Anarachism-flavours tend to be universally terrible because they pre-suppose unnatural behaviour on people and in practice will devolve into some flavour of top-down collectivism.

You think capitalism is natural? And is top-down "individualism" better than top-down collectivism?

Also, there are real-world examples of libertarian socialism, like the Zapatistas and Rojova. Not ideologically pure, no, but certainly not authoritarian shitholes or capitalist dystopias.
