I'm trying to understand it, but I can't. Latitude and longitude can be used without an internet connection if you can get a GPS signal. If you're a boy scout or doomsday prepper or 1800s explorer who fell through a wormhole, and have a bit of time, you can use the sun, stars and a makeshift compass to get a good ballpark. It's a system which only requires you and your counterpart to both accept the contract of the coordinate system. As many others here have pointed out fuzzy.enlarged.testicles doesn't mean anything unless we both have access to W3W, and then the directions which come from me needing to get from hairy.baked.potato to you at fuzzy.enlarged.testicles uses GPS. Because giving someone a print out of all the W3W plots they need to pass through is useless, because those phrases don't mean anything, because the system isn't contiguous or addressable. It'd be like every house on a street having a different, non-contiguous number, different name and different postal code (134 wallaby 53217 next to 5678 futon 44444). Or for the Londoners, if the postal districts didn't increase as you moved outward. It's a bad design with too many assumptions.
