Panarchism

Panarchism is a political philosophy advocating the peaceful co-existence of all political systems, and allowing people to switch between them as they choose. Panarchism has never been a developed political movement, nor even a developed philosophical position; but nonetheless some people have proposed it.

(It can be argued that panarchism would be unlikely to work, due to the inherent expansionist tendencies of most political systems, and the need to find some way of dividing territory between the different systems, and solving disputes between them, which would some super-political system to be imposed on everybody.)
