I've found the most freedom on the fringes of the earth. Rural South America and Kurdish Syria to name a couple.

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.
