It's not the size (of the address) that matters, but how you use it. Whether you assign one IPv4 address per subscriber and make them use NAT, or give them each a block of a zillion IPv6 addresses, the routing cost is the same. If you really believe it's the total number of addresses that determines the size/cost of the routing system, you'd better start working on moving the world away from IPv4 to IPv-1 with 17-bit addresses.
