I'm a big fan of charter cities/SEZs and new city/country projects but I'm more skeptical this is a practical avenue for making money. There are plenty of established jurisdictions to do this (e.g. basically all the former British colonies, a few American states) and the 'infrastructure' of lawyers, accountants, etc. who know how to deal with it are already established. This is the same reason I don't get why people are bullish on e-Residency for Honduras, Liberland, etc. What's the real value prop of incorporating an entity in these places?
