The lat and lon are actually 3d since we live, up to a first approximation, on the surface of a sphere. The correct way to think about it is xyz in a reference frame anchored in the center of the Earth
If you accepted that nothing exists at the north pole, that’s enough to obtain meaningful 2d coordinates for a location:)
Not workable in practice, though!
