The question is, why there's so much defense of state legitimacy on cognitive level. As if "it's necessary evil" vs "it's a universal good".
It's still controversial to say that "taxation is theft".
And why is social contract theory still relevant, if nobody ever signed that social contract?
If people were honest they would say "yes, taxation is theft, and the state is coercive, but it's necessary because power vacuum is not realistic", but they tend to say "no, taxation is not theft, because it's fair, popular and necessary".
It looks like people would rather silence libertarianism by not acknowledging the compulsory nature of political organisations... rather than simply ask questions about how feasible a truly free world is.
