Absolutely. Though even calling them in Arco capitalist is still to generous and a blight to the term anarchist. (I've met a few anarchists that were too idealistic and unreasonable for their own good. But they are generally pretty chill, reasonable people otherwise.) They are no true libertarians. Actual libertarians push not just for freedom from things like government. But also the freedom for everyone in society to be able to do the things they desire. One without the other is not a libertarian.
