I think that's the answer - the concept of local calls still exists as
there are still people on legacy tariffs (and possibly the very rare
current one) that makes the distinction. However the vast majority of
current tariffs do not make any distinction between them.

With the way the modern network is set up, as a technical concept it
doesn't make a lot of sense. There's no guarantee that a "local" call
will travel a shorter path or use less equipment than a "long distance"
call - especially if it's on another provider's network, when the call
may cross the country to a gateway between the networks and back. With
VoIP numbers, there's no guarantee that the "local" number is even in the
area that the code belongs to.
