Anarcho capitalism is the only real anarchists, the philosophy was formulated in the 80s by Murray Ruthbard, who lived most of his life (if not all of it) in New York.
All other "branches of anarchism" are fake, the biggest one is anarcho communists, which it seems like is the branch described in the links you provide.
Again: Anarcho capitalism is the only real anarchists. Also real true cryptocurrencies like Hive and LasseCash is truly anarcho capitalistic.
We are all in the same boat, icymi.
