Searching a database for a way that surrounds a potentially enormous area (certainly enormous in the case of country) when you want to find out "what city/country/... is this in" is *far* less efficient than simply looking at the tags. Plus, Addresses are not always as straightforward as you make out, it's not possible to tell which administrative areas should be included in an address by simply looking at which ones happen to encompass the building.
