Hm, I think if you made a list of all the countries that are a decent place to live that the vast majority of them would have large central governments. All of which use force to collect taxes for things like universal healthcare, social security, public schools.
I'm pretty sure NAP says that the government can't force you to pay taxes for public schools.
"They do but the larger governments tend to do worse."
Larger compared to what? I think places with the smallest most ineffectual governments are all hell holes. Every decent society has a large central government. The "economic freedom index" is a bit of a misnomer. They define freedom as a government large enough to protect rights. So right out the gate freedom is redefined as a large government that uses force to impose civil society.
Let me pick one example. Your freedom index lists Switzerland as "Free". Switzerland has government imposed universal healthcare. That sounds like a lot of government to me, how about you!
One last thing, none of the countries listed as "FREE" are anything close to a libertarian society based on the NAP.
I'm pretty sure NAP says that the government can't force you to pay taxes for public schools.
