Interesting.
Changes: it would do what bitcoin did to the monetary sector. Lots of benefit, just by observing what bitcoin has brought to global south. Fundamentally, no closed layers above the protocol code which represents the constitution. Hence, power back to individual.
Fails: to get there. People in the existing layers prevent it from happening. The gov is the only “legal” entity that can hurt you. Thus, will be more challenging to build the protocol. More threat that one Bitcoin core devs have got. This seems to be solvable if one builds a new country. But as for now it is really not a country without military, so will be under some countries umbrella with legacy gov anyways
