You're trying to solve with technology a problem that lives in the abstract human world. Even the simplest possible case, you make a physical unique object that you define as conferring ownership to the person who possesses or controls it. Someone steals the object, now the person in possession of the object isn't the owner. There's this allure of trying to tie this abstract notion of ownership to a physical thing but it's breaks down immediately. It doesn't even work for physical objects.

Automated enforcement of ownership rules is completely tangential to the actual problem you're running into. You own a physical book, you make a copy then sell the book. That's a copyright violation, no "verification" or whatever nonsense needed. What happened in regards to ownership in this case is already clear. Companies sure do like DRM but it's as much a pale imitation of ownership as anything else.
