As the saying goes, there are many ways to skin a cat. If you hand over the
packets with destinations in a certain region to an entity that handles
that region, such as an internet exchange, then you're indeed using a
different economical model than we use today.
But you can also do all the geo stuff in your own network. For instance, if
you have a world wide network, you could split the world into 10 pieces and
handle routing for each of those regions only within the region. The other
regions then use an aggregate to get the packets to the right region. You
would of course have to peer with other networks within these regions or
break aggregation. But then, if you have a world wide network you're almost
certainly peering in more than 10 places as it is anyway.
