That would only be true if IP addresses were geographically assigned,
which they aren't.
You know, you could assign IPv6 addresses in a strictly geographic way
and you'd have more than enough for everyone, everywhere, with very
simple routing. But of course that won't be done.
The actual cost driver here is a need for an operator (e.g.
Postal Service or ISP) to maintain a list of all existing addresses
to be able to provide their services.
Not necessarily. If the addressing is strictly geographic--n
addresses for each area of m square metres on the planet--routing
would be very simple and wouldn't require much in the way of tables.
With 78 bits, you can address every millonth of a second of arc in
latitude and longitude on the planet. That's an area of about 0.00095
square millimetres.
