You also need to distinguish between the contexts where you need addresses versus coordinates. Lat-longs, plus codes, and word-encoding schemes are all coordinates -- they identify a point or area on the globe. Addresses are last-mile navigational instructions. "Apt D, 123 Main St" allows anyone with local knowledge to navigate efficiently to the location indicated: first they drive to Main Street, then they proceed along the ~monotonically numbered parcels to 123, then continue to the apartment labeled "D". The advantage of coordinates is that they don't require local knowledge and can identify arbitrary points; the advantage of addresses is that they encode instructions for land navigation that takes into account which parts of the land are passable.
