Navigation using an address also works without cellular otherwise Garmin and TomTom devices wouldn’t exist.

I think an address is much easier to understand for a child.

Using an uncommon for most people method of location identifier brings problems of its own. Sure Lat/Long is familiar to us, but I’d guess the average person is unfamiliar.

Like I said, I like the idea but it doesn’t come without its own problems and addresses aren’t as useless in this scenario as implied.

Fair points. I'd still register GPS as more generally useful and usable.

your assuming they dont have both. people dont memorize their gps coords and theyre not easily findable with a phone. redundancy, defense in depth.
