I think anyone who claims to be an anarchist is talking nonsense. I'm not sure what stripe of anarchist Moore is, but most present anarchists realize that a minimal form of government is necessary. Since anarchy literally means "without government," such self-professed anarchists are not really anarchists. Hence, they are talking nonsense. If Moore actually believes no form of government is necessary, then he is either preparing for that day by stockpiling small arms in his basement, or he is still talking nonsense. No society can function without some form of government. Anarchist actions can be a means to an end, i.e. to violently overthrow a corrupt government as in V, but once the government has fallen another form of government must replace it. Anyone today who believes that England or the U.S. has reached the point where a violent overthrow of the government has become necessary is talking nonsense.
Of course, he could just claim to be an anarchist to mess with people. That I would wholeheartedly approve of
