The only thing that speaks to how many billions of dollars have been
spent developing products that work around the problems introduced by
NAT. There are a great number of products and protocols that either
behaviour poorly behind NAT or have had to have some ugly hacks to
make them work. We shouldn't simply accept NAT because of inertia from
its use in IPv4. ISPs should take a leadership position in actively
discouraging its use, as we all win in the end.
