Because you have private connectivity with other companies and you need guaranteed unique IP space.  No, really, you 
can't implement NAT for every possible scenario and even if you could you'd need publicy routable space to NAT it to, 
or you run into the same collisions.

I have worked at companies that have in excess of 4k private interconnections with their clients. Unique IP space is 
the only way to make this work.
