You really think most people live at locations without addressing systems? How can we even prove that?

The only locations I'm aware of that that is true are: very poor parts of Asia, Africa, India, and maybe some of the favelas of Brazil.

With essentially all of North America, South America, Europe, and much of China, along with all of Japan, Australia, being covered by an addressing system.

I'd wager 2/3 of all people live in a location with normal addresses.
