Good solution.
But not for inexperienced users. They'll just enable everything to get their files.
Google is doing great job for tracking companies (like Google itself).
Usually here are two numbers for each address (there are even more specialized but it's not common): landmark - blue background and descriptive - red background (see [1]).
"Blue" ones are better for orientation, they are in sequences, counted from 1, which start on the end of the street which is closer to some remarkable point in particular city (e.g. river at Prague). On one side of the street are odd numbers and on the other side are even numbers.
Red ones are more "administrative" so they are not suitable for orientation. But at some smaller towns/villages or some parts of the cities are the only ones.
Those new locating systems are solving problems which most of the people don't have. They make it even worse.
We have street addresses in the most of the cities. In case someone call me if I can come to e.g. "Delnicka 43, Prague, Czech Republic" I know immediately where it is and I can say I can be there in 20 minutes. In case she tell me "mission back envy" I must connect to the Internet and check where exactly is it. So I must have some device and connection. And in emergency situations every minute counts.
For places where street address system missing there is geographic coordinate system such as GPS which is widely used and acceptable by (if not all) the most of emergency services. And it's not GPS-dependent only, such coordinates you can find out in many ways (e.g. paper map, position of the Space objects etc.).
