Widen your mind :-) - and indeed, I am making this case.  Multiple
different scenarios where NAT is making life much easier (or enabling
a solution at all that might not be otherwise possible).

And none of this is the trivial case of conflicting RFC1918 IP address 
usage in enterprise VPN scenarios.

Or the case of destination NAT used for load-balancing...  (still NAT,
even if not N:1 source NAPT).
