Arcadia is a state that is divided into semiautonomous zones, organized on the basis of political philosophy. In Arcadia for example, civilisation is composed of a libertarian community with a fully deregulated economy and low taxes, an anarcho-primitivist community where people live in a state of nature with no laws, and more. There is a neutral central entity whose only duties are to prevent communities of Arcadia from causing harm to each other, ensuring freedom to move from one community to another, and preventing unwanted ideological contamination. Information about each zone is disemminated and assumed to be accessible to all.
