Feudalism is about the localisation of military and legal aspects of government. Libertarianism is about trying to restrict the power of government. Slavery requires a strong central government to be enforcible. Feudalism and Libertarianism are both anti slavery.
None of the people you have named are libertarian, to be fair. Also, for someone arguing a potential dystopia being brought about but these people, you sound like someone very willing to create your own, by arguing for silencing everyone you disagree with.
It’s not a matter of silencing people I disagree with, it’s a matter of having integrity in publishing. Because the “we all have a right to free speech” argument has been distorted to mean that everyone should have what amounts to modern day prime time access even though they’re a bunch of liars and grifters and, in some case, just kind of stupid.
