It never existed in the first place. You just were unable to see the machinations behind the scenes when all of media was a newspaper and 3 TV stations.
Anywhere with any real government though, it's dead. My theory is the period of classical liberalism in the world was largely a result of the brief period where firearms were the main form of warfare, which represented a short period in history where violence was most decentralized and the government had the least leverage. Before that it was years to train archers or swordsman, after that fighter jets/ missiles / technology tilted back in power of government. In the golden era of the age of the firearm one person was basically one vote of violence (giving the populace the greater leverage); whereas before/after that time each vote was heavily weighted by a government actor.
I grew up in a place you could call “rural South America” (specifically in a rural border town between Brazil and Uruguay) and at the time didn’t feel free there, but these days there’s a lot I think I could appreciate about the place if I were to go back (I’ve been living in the US for the past 13 years).
It's a very common usage in America, focusing on "Freedom from X" rather than "Freedom to do Y", the latter of which often needs some sort of societal protection, most often provided by said government.
