Others have pointed out that there are a lot of things that we 'own', but that fail this definition for regulatory or safety reasons. I don't think that this is a good definition. To most people, ownership means legal control over physical possession, and the right to transfer 'ownership'. Apple can't legally require that I return my iPhone to them, just as Toyota can't legally require that I return my minivan to one of their dealers. They 'belong' to me - I 'own' them and control who possesses them.
