Care to show the documentation of who holds actual title for, say, Granny's 1951 Buick?
Please provide a citation of evidence to back your claim...
If Granny OWNS her car, (retains all rights, title and interest in the property) -- then she may do as she wishes with the property.
Tell granny that you are going to send over a policeman and see what he does when she tries to remove the VIN plate on the vehicle she 'owns'.
