Of course it worked. Any authoritarian intent on banning a book just could give the spurious reason that "the library does not have enough room" and then there is no censorship ever, according to the original post. See how childish that reasoning is?
I largely agree with you for the time being; I think right now we are in the "dumb authoritarian" phase because Trump, Musk, Thiel can't keep their mouths shut about their true motivations. I fear that there are probably a smarter generation of authoritarians who are more clever (Russel Vought, for example), and not in the spotlight, waiting for their time to ascend.
The loud ones come first, because they have to corrupt the minds of the youth and the mentally weak so they can have a movement.
