No, the reason we have NAT is because it's a lot easier for novice network administrators to divvy up and route 10/8 than it is 208.x.x/20. Any leaf network can get all the non-portable addresses they want, for a price.
There's also a general perception that NAT increases security; some "security" companies go so far as to say NAT removes the need for a firewall. It's amazing how many network admins believe this.
Some also say that firewalls/nats remove the need to secure your systems.
