Imagine a nation with a blockchain governance democracy

What do you think on a country where every registry is on blockchain,like taxes or bills,and especially there is a popular governance based on blockchain to governate the country making laws by everyone.Maybe with some little parlment just to put a neutral third subject for moments when people are divided on a undelayable decision must be taken.Off course in this country the national currency is a crypto.We can really have a pure and real democracy here with this technology,I know it's something most of the people can't image.You decide and vote not for a politcian but directly for the politics,thats can be on or the better use case of this tech.Do you have other ideas for a nation 2.0 like this?Pro and cons for this?
