I'll try my best attempt at a steel man: It can be a useful way to convey location information via language (spoken or written word), when there isn't a direct digital connection between sources. That's genuinely a non-negligible use case.
So if you see an advertisement for a restaurant at giant.purple.monkey, you can get there. Or maybe you're coordinating plans on a non-smartphone call. Or you could put the location on flyers (a QR code could work, but lots of people hate those). Or you're dictating a location to a smart assistant (Mercedes-Benz did a partnership, and AFAIK the in-car assistant accepts W3W locations; I don't know for sure though, I use android auto in mine; disclaimer: I work at MB).
In practice there are problems with plurals, homophones, and other similar pronunciations (did he say heavy.monkey.dress (near SF) or heavy.monkeys.dress (near LA)). I think realistically W3W is almost never the best option, but I do quite like the idea. Maybe if they did a better job filtering words to avoid collisions, and made it 4 words? I imagine it could actually be a pretty memorable way to describe a location if it were something like adjective.noun.adjective.noun, and with fewer near-collisions in the library (heavy/heady).
