Like I said, you can start with Econ 101, and work your way up from there. I don't know why they don't just give it a try. It's more fun to be open-minded than think you know everything already.
To me it is a shame to see people so stubborn and resistant to thinking differently.
Many different economic systems have been tried all across the world and throughout history. Given all of your reading, surely you could point to an example of these theories being tried out in a real economy and succeeding?
As far as I know, there are no successes. Most attempts couldn't have open borders, because everyone would leave.
(And yes, there are lots of other factors, like corruption and the natural resource curse.)
Essentially, claiming that your economic theory will only work once a dramatic, complete, state-wide change as occured is a non-starter. Nations advance by degrees, and if there aren't small moves that can be made towards the goal that provide evidence that the theory is sound, it would be foolish to believe that big moves will fair any better.
I would genuinely like to see examples of where libertarianism ideals have been tried on a small to medium scale and been successful. And if there aren't any, same question as to jasonisalive: why is there such confidence among libertarians that it works in the real world?
To me it seems that only you talk about libertarians, while jasonisalive talked about generic economic research.
(Wikipedia confirms my belief that libertarians are quite heterogeneous and it is more of a political philosophy/ideology than about economy anyway.)
Subjects based on complex data sets without possibility of experiments are hard to verify for people external to the subject. (Famous other cases are climate science and evolution.)
From that, left wing extremists (I don't know anything about your position -- you might argue against "free market", which was the subject here or "libertarians" which you mention?) sometimes write conspiracy theories that all the academics in economy are idiots and/or in a conspiracy.
So let us skip this and instead look at practical results:
If you have a country with low corruption, competent state administration and a capitalist system you might get a good economic development. Otherwise, you will not.
