I would argue anarchism has been tried in the past, it was simply called feudalism. Since it lead to the Dark Ages, there's not much support for it nowadays.
That is a really hot take. Anarchism developed as a response to industrialization and the transformation of society caused by the adoption of capitalist modes of production.
That's absurb. Anarchism is a system completely without land ownership (i.e. "property is theft"). Feudalism is a system based almost entirely around land ownership (named after the word feodum meaning a grant of land in exchange for service).
