I can't, because I can't see how it does, especially given widespread use of
privacy extensions.

I wasn't there at the time, but my understanding is that a variable-length
address field is harder to parse in hardware than a fixed-length field.  It
is impossible to imagine the Internet of 200 years from now, but to get an
idea of how 340 trillion trillion trillion addresses could be used up:

It would cost more and be slower.  Maybe this depends on what you means.  I
take it to mean that each sovereignty would determine for all networks with
it what protocols would be used (or they would decide not to decide).  For
users in that region to reach content in another region, their traffic
(possibly beginning at DNS requests) would have to go through some kind of
gateway or translator.  This would handily centralize all traffic for
national authorities to snoop, and would increase infrastructure costs by
forcing a route (rather than selecting cheapest path), not to mention the
cost of the gateways.  It would impair performance due to the latency of the
gateways, and by forcing a router (rather than selecting the best path).

It would allow governments to have more control over content.  It would be
awful for the Internet.
