Sounds like you are rebuilding the state one basic right at a time
A-hyuk a-hyuk... you got the stoopid yank thar... huh huh huh.
A land database is is just that. a database. You can have competing courts (called arbitration agencies) and police forces (called security firms) without a state. I'm not saying we don't need the services. I am saying we don't need the monopoly that currently provides those services.
Arbitration agencies can only compete if there is a single set of laws for them to follow. If you have a single set of laws you have a state.
