Except we don't hold the z coordinate in the OSM database. There are other addressing schemes such as three words but using the lat and long for the address is much simpler. Encoding it with OLC gives you the advantage of a more human friendly looking address.
There are issues which have been discussed in OSM-talk about adding tags to the database. In a conventional house number street address you can expect that number 4 main street will be between 2 and 6. Unfortunately if you have no street names and no house numbers it gets more difficult to confirm you have the correct address using anything but a lat / long based scheme.
