Personally, I find his Linux and privacy-related endeavors commendable, but I widely disregard of his political stances.
The way I learned it is that anarcho-socialism is the extremist version of leftist libertarianism. A moderate libertarian doesn’t mind the existence of a government, as long as it is limited. As for the anarchists, I know that they exist and I know that there are both on the left and the right, but I don’t have interest in reading their literature (it might be a cool theory to read, but the fact that it is so far from practice makes my interest in it practically vanish).
I’ve never heard any libertarians be referred to as “moderate”. As far as I understand it, “libertarianism” already includes a radical worldview. Wanting less government an simultaneously more government control IMHO sound a bit oxymoronic.
As an anarchist myself, of course I disagree with your stance on the practicability on anarchism. ;)
I’ve never heard
Well, looks like conversation is impossible then. Unless you have better sources, those two words are not 100% the same. Anarchism is a specific word, coming from the greek anarkhia, meaning “without a ruler”. Libertarianism, on the contrary, is a more broad word, since liberta is latin for “freedom”.
This is not about the dictionary, but about historical movements/strains of thought. The french “socialisme libertaire” is the term they used in 18th century France. And libertarian socialism aims for the freedom of all people from rulers.
