Devil's advocate hat on: NAT (in its most common form) also permits
internal addressing to be independent of external addressing.

The side effects of that are not necessarily desirable (loss of
end-to-end connectivity, performance issues, limitations on simultaneous
connections etc etc).

It seems to me that it is this property of NAT that people are most
loath to lose. And why ULA looks tantalisingly delicious.
