In order to preserve the freedom to leave a group, no group can be so large and pervasive that there is nowhere else to go. There must always be another group to go to, or a space in which one can start one's own group. Monopolies of any kind are to be dissolved. A uniform principle is that people can vote with their feet. That is, there is always a choice of different circumstances and systems to live by.
People go to the area or group that best fits their personal preferences.
They participate and support the group community they've chosen to be part of. If they change their mind they can always go somewhere else. The general rule for decision making is that decisions are taken by those who are directly involved and affected. That means that decisions about local conditions of living are taken by local residents. Representation is generally used to allow smaller groups to participate in affairs of a larger scale.
