There is a fundamental equivalence between unique pictures of a cartoon mice and automobiles. Any automobile can be mapped to any particular unique cartoon mouse picture based on the method of encoding chosen.
Automobile ownership is saying that I own this particular result of turning a unique cartoon mouse picture into usable car regardless of starting cartoon mouse picture.
This is to say that we can't tell without actually decoding the cartoon mouse picture so we are in fact asserting that there is a chance we own any and all cartoon mouse pictures if someone later publishes the encoding that would turn your cartoon mouse picture into an automobile.
