Possibly some customers may react this way, but I’m thinking many more would 
ask “what does it take to enable it?”  Most are reasonable and show good faith, 
even if an equipment swap is needed.  And if the demand for IPv6 is there, the 
providers will get the work prioritized.

IPv6 doesn’t help anyone get access to their IPv4-only customers.  (Too bad 
that it doesn’t.)

My point was that, if eyeball networks start charging a premium for IPv4, their 
likely first customers to be charged are business customers not behind CGNAT.  
Those that don’t wish to pay the IPv4 premium would have to force *their* 
customers to go IPv6. That would be a much more difficult conversation than 
simply paying the premium.  So out of all the forces at work, which gives way
