It doesn't. It simply returns one's power to decide how to spend one's money. States are known to thrive on exactly the opposite.
It will be interesting what "states" will look like in a bitcoin world. States looking like they are today will certainly have a hard time not going bankrupt when everyone decides for themselves how to spend their money, instead of figureheads wasting it on bombs.
States will treat Bitcoin the way they treat gold or any other commodity.
Gold-based states and paper-based states look very different. Especially if you change the one parameter tech level = post industrial revolution. It will be interesting indeed, but I'm confident it will be different.
