Inside the city, you see lots of longer prefixes from that city's
netblock. Outside the city you see only the single aggregate prefix.

Monopoly? Not necessary. Yes, you need to have universal exchange
of local traffic in the city but that can happen through private
interconnects and multiple exchange points. No need for a monopoly.
The major change is that providers which participate in geotopological
addressing would have to interconnect with *ALL* other such providers
in that city. This would mean more use of public exchange points.

Also, I think it makes sense to have a second regional layer
of aggregation where you group neighboring cities that have
a lot of traffic with each other. I think this would result
in no more than 20-30 regions per continent.
