I think this is a pretty interesting comment. It sparked the idea of a 'tax-free' zone in each country in my head. Like a area of each country with no government infrastructure or intervention. The proportion of population living in these zones would really give a good indicator of how the countries are treating it's citizens. People would be free to cross this fence whenever they wanted.

But in reality I don't think any country would want to give up land for such means.
