They already are. And, depending on the network, have for eons. Have you  
checked the IP used by your cellphone? (the last few times I bothered to  
look... somewhere in 29/8. I thought that was really funny.)

Simple: Money. It's cheaper to install a $100k NAT appliance (or several)  
than it is to replace 16mil CPE devices, plus all the engineering,  
testing, and customer support "training" (read: BS scripts to follow.)  
AND, your customers aren't having any trouble getting where they need to  
go. Sure, there will be the forward thinkers pushing for IPv6, but not  
because there's some IPv6 only place they need to go (or be.)
