Please explain how you intend to eliminate manual renumbering for 
corporate internal networks every time they change ISPs.

(And note that RA and even DHCP6 don't fix all the manual setup of 
things like "what is the address of the intranet web server".)

There is a real cost to this, and the cost of a NAT device is pretty 
much paid off the first or second time you're forced to renumber.
