I'm not sure what Gary is asserting. However, I suspect his assertion
is similar to mine...
I'm asserting that NAT creates the following costs borne by people
providing services to NON-NATTed customers who have nothing
whatsoever to do with NAT:
1. Additional troubleshooting difficulty/cost (web sites, services,
network providers, network providers selling to web sites, etc.)
2. Additional software complexity (ISVs)
3. Decreased security (inability to correlate events/logs)
4. Increased legal costs (see 3)

Even in a free market economy, you're not supposed to dump toxic
chemicals in the river upstream from my water treatment plant.
