It feels like it doesn't really solve a lot of "address" problems. Addresses typically correspond to a single building or subdivided unit. Your home/apartment/factory could overlap several GPS grid squares, and then people have to decide which one is canonical or record all of them. In most places, addresses are roughly sequential. This gives you the ability to reason relatively: If I just walked past stores numbered 2503 and 2505, and I'm looking for 2751, how far away am I and am I going in the right direction? Easy to estimate. If I'm looking for manatee.fracas.bologna and I'm at porkpie.hamster.obnoxious, I can't make a conclusion. Sequential addresses also make sorting and routing easier. Group the items by street name, then sort by number. No technology required, and easy to monitor and fix if it gets upset. Shuffle a few envelopes in a W3W mailbag, and it's going to be a lot harder to get it back in order.
