Except it actually is reality?

Anarchist collectives in Spain are the biggest example of anarcho-syndicalism existing and thriving in history, hell the CNT even exists today. I’d recommend reading the anarchist collectives by Sam Dolgoff if it’s something you’re curious about, it’s a fantastic read.

More general anarchism exists today in the Zapatistas, and probably other groups I’m not aware of. If you extend that to just anarchist collectives then I can rattle off a list of them just in one suburb of my city.

It’s important political theory, and it works. Just because you don’t like it doesn’t change that fact.
