It's a pun, but that's all. The plain reading of 'We are not talking about eliminating other types of states. We love most states, especially yours! Also, "hash" is another technical term and has nothing to do with cannabis.' does not indicate a serious commitment to anarchism.
Daniel J. Bernstein, who is hosting the page, doesn't seem to be public about his politics, but is probably not an anarchist. Since it's associated with several universities, it is probably just a bit of CYA combined with tongue-in-cheek.
