My dude, Hungary being fined by the club it signed up for makes your point only if your point was that the library dominates you with their late return fees. Not only did Hungary consent to these rules, it could've at any point withdrawn consent through Article 50.

Additionally, this is from 2024, Hungary has since democratically elected a government on the express platform of getting rid of the wannabe dictator that got them fined.

You've mistaken the mere existence of enforcement for domination, just like you keep mistaking ideological preference for natural law.

Also notice the words you used: "attempting self-determination". Weren't you just making the point that might makes right? In that view, Brussels has the power, Hungary doesn't, News at 11, yada yada.

But nobody actually lives by "might makes right", you included. As soon as its somebody you're sympathetic to, the cold realism drops and we're back to consent and sovereignty. That is my point. It's just a line people use to defend power arrangements they like, to be dropped for ones they don't.
