We require only a property database

We don't need the Government. We need a database of property ownership, regulating infringements where a person has exceeded the (global) cap.

Provided we have the means to deprive someone of (ownership of) property which (the exclusion from) is adversely* affecting others, and the group, then Government is not required. If someone owns too much property, that is a risk for them. Property should be limited, for each individual across the globe.

The sale of property must be contingent on the purchaser owning no more than the Global Cap. If someone can demonstrate that land in multiple jurisdictions is owned by a person exceeding the cap, then the property owned by that person is reduced. There would be a central database.

A database of property ownership, that restricts harm to others (by hoarding property) is sufficient for a peaceful Society.

*More than is commonly acceptable.
