I think he was a little too far up his butt on this one. Laws are created by people and followed (or not) by people. It doesn't matter what the internal logic of the system is, fascism means dismantling it and replacing it with direct power.
Fascism is created by people and followed (or not) by people. Every government/system is created by people and followed (or not) by people.
Is that true? Why is that the label and not "monarchy" for example?
I think you've transposed fascist and authoritarian. Fascism isn't a synonym for authoritarianism. Fascism and some types of monarchy are both authoritarian.
