I’m not an anarchist. And we don’t live in an anarchy. And we will never see a true long term anarchist society of any real scale in our lifetime. That is fine if you are talking about some idealistic utopian goal. But I’m talking about the world we live in now.

And they didnt say that they shouldn’t be necessary or viable because there is no central goverment authority to advocate to. They said they shouldn’t be allowed. Those are two different stances (and not very anarchist to talk of disallowing advocacy roles).
