Not being able to factory reset a device that you have in your physical possession is not reasonable, in my opinion You have a car parked outside your house. You have no keys and no paperwork proving ownership, nor is there a record of you in any central repository. Should you be able to just claim it by virtue of physical proximity? I think most people and most legal systems would say no.
