Yes, it doesn't matter how you try to explain it. The simple fact of the matter is if you don't want something stolen then you would protect it. Doesn't matter if its a car, money, house, possessions, you name it.
If you are too lazy to take the extra minute or two to store your car in the garage then you run the risk of having it stolen. There is no logic involved, it is all common sense.
Which means you're agreeing with him that it's fine to steal it when the owner isn't bothered about privacy?
