Well if you’ve already read them and know the ideas then of course those books wouldn’t be super entertaining or thought provoking. But for people who are new and actually interested in a real economic foundation, those are great places to find grounding from the Keynesian shit people are fed.

Those are recommended frequently because they are often completely unheard of for new people into the space. I still know people who majored in Econ and have never even heard that list of names. But of course, it they aren’t looking for economic grounding or something to explain why everything they know about money and the state is nonsense, then those books won’t be of much value to anyone. But nobody is going to pick that knowledge up from Shakespeare.

TL;DR - That list is recommended because those are generally the ideas and arguments that normies have literally never heard before (Rothbard, Hayek, Mises, Rand, etc). Thus, they often result in people’s worldviews being shattered, because they are extremely strong philosophical examinations, imo.
