Some people believe it is. Who am I to tell them how to run their 
network? They block facebook and yahoo. I, unfortunately, can't. :)

People will then have a false sense of security with stateful firewalls 
that perform no better than NAT, just without the address translation. 
The type of stateful firewall with or without address translation will 
not suddenly make people become wiser and implement better security 
policies. Vendors will always make a cheap setup which people will use 
and consider themselves secure.
