What makes you think we're not already doing all of the above?  :)

As I said, the problem is an ISP doesn't have control over what their 
customers choos to purchase and run in their own network.  An ISP can 
setup a fully dual-stack network everywhere in their own infrastructure 
but if the customer chooses to use only NATed IPv4 (for whatever reason) 
on their own equipment, it would be a foolish ISP that insists the 
customer must change out all their equipment.  Users will migrate to IPv6 
in their own time and their own way.  But if they happen to be behind some 
$50 NATed IPv4 router, it behooves the ISP to accomodate those 
out-of-the-box-running-Teredo devices as best as possible instead of 
relying on somebody elses Teredo relay.
