Circles of Sharing
These circles are likely to have multiple depts and many interconnections. Anyone can be part of different circles while also part of the same one.
An example could be sharing financial resources into a collective pool that can be used for common purposes or specific things such as insurance or investments into the conventional economy. Think of community banking or financial cooperatives.
Another example could be housing. A group of people that have access to multiple housing world-wide or in their localities. Members have access to these.
