Please do the math.  Or just look at 100 cakes and try to imagine how
many the kids can eat before they really *really* do not want to eat more.

I was talking *networks*.  Every *network* has an effectively unlimited
number of addresses inside, and we have more than enough networks for 
every human on earth (vastly more than enough).

Because we can.  And it enables new uses and applications that are 
unthinkable in a "everything hides between two layer of N:1 NAT" world.

If we do not want that, we can just stick to IPv4 - with 100:1 carrier-grade
NATs in the access networks, the roughly 3 billion usable IPv4 addresses
are sufficient for a consumer-producer-style Internet (they just need
to be redistributed better).  I don't think this is a desirable path, though.

have you enabled IPv6 on something today...?
