If you are at (random1, random2, random3) you will have even less idea how to get to (random314, random42, random7) without accessing a commercial site on a computer of some kind. In a small town it's not so hard to figure out from street addresses, or you could ask someone (something that would surely be difficult with what3words). In larger places there are paper maps, and free digital maps from google and openstreetmap and bing and so on. If a digital map provider has a default address in the middle of the ocean (like lat 0, lon 0, for example) then they have surely gotten enough complaints to provide a better solution from address matching technology. Multiple locations in different places with the same address are a problem when no more information is known; routine address finding in a specific place would not have that problem.

How about a three-word system that varies systematically on a global hexagonal grid, or a four-word system that varies with easting and northing on a global map projection (a projection like what3words uses). A systematic three-word system would have words varying in alphabetic order along each of three axes of the hexagonal grid. Some locations would have duplicates or triplicates (e.g., at the origin of the addressing) of words. You need just the alphabetized list of words to find neighborhoods of a given hexagon (of whatever size the system uses), and therefore spatial analysis in hexagon space, or coordinate space after simple, free, conversion to coordinates. Global hexagon systems exist, see http://www.discreteglobalgrids.org/ A four-word system could have a lower and higher order address in both easting and northing using an alphabetic ordering of words. Either of these would be easily adopted if the word lists were freely available, in various languages of course.

There are many, many ways to create unique addresses that don't require commercial software to have coordinates from which you can measure distances to things, find neighbors, and do all the many other kinds of spatial analysis. As an example of a spatially rational system of addressing check out Dubai's Makani system of 10 digit addresses with 1 meter precision.

The reason that probably there have been no answers is that this system is a very poor idea for addressing. It takes the spatial context out of addressing. Go to a place you know; I went to my house. I have at least nine different, totally unrelated what3words for my house. In order to do anything useful like finding distances, calculating buffer zones or neighborhoods, even finding the address of anything, you have to use a proprietary system for easy access to locations and spatial context.
