Yes, perhaps some Mises/Rothbard is the dividing line that someone needs to actually know something about the Austrian School and stop holding the ridiculous ideas this kid puts forth.
But I’m glad you recognize the hyperbolic nature of your comment, although I’m not sure you appreciate just how extreme it actually is, as I’ve mentioned multiple times, including here and here, I know of university professors of economics…who have never even heard of Hayek. To suggest that “everyone” knows of Hayek and his association with “the Austrian School” is to suggest that he is a “household name”, at the very least in academic or tangentially related circles. And I can assure you he’s absolutely not.
I’m well aware you didn’t literally mean “every single person on the planet”, but I would still argue you’re way off…to the point of basically being incorrect.
