Really interesting link, thanks for sharing.

Anarchism does not (necessarily) call for a total lack of organisational structure, first and foremost it calls for the abolition of unjust hierarchies. I think a lot of anarchists would broadly agree with the main points of that article.

If you think there is no viable alternative to captitalism, I'd highly recommend the book "Capitalist Realism" by Mark Fisher, which tackles that very subject :)
