What world do live in? Yes, we extend the life of IPv4 by increasing the numeric range. As for "only needing port 80", I'm not really sure where you've been for the last decade or so. There's are hundreds of services using different ports, and tunneling them all makes absolutely no sense. Yes, we don't really need 65k ports, but stealing bits in the header from them is the most ridiculous thing I've heard yet. List of registered ports: http://www.iana.org/assignments/port-numbers <http://www.iana.org/assignments/port-numbers>Also take into account public access *nix servers, with people running their own services on whatever port they've taken or been assigned.
