I think that you answered you own question: if you own the space over you house up to the tallest building, then, I flying on a plane, higher than the highest building in the US, can take pictures of your property, inside your 20 foot fence, totally LEGALLY, just like I can take a picture of your fence LEGALLY from the street.

Your argument breaks down, because, if you truly want to protect the luxury vehicles, you need to build a ROOF over them.
