Limited Common Property Regime
Definition: A Limited Common Property Regime is a defined set of rights and obligations in a shared property, which allows a specific group of individuals to benefit from its use.
The Limited Common Property Regime is often applied to common-pool land or resources that are indivisible because of their small size, tradition of commons, or physical indivisibility. Examples include condominium parking lots, traditional shared fishing grounds, or riverbeds.
The Public Domain could be phrased as this type of legal construct, a rare legal space for collective holding of land. If group ownership can be framed in a flexible and non-exclusionary way to include everyone in the world, this solution might be viable.
It could be argued legally that the community still would maintain the collective right of alienation with regard to non-participants.
