They could trace it back to a physical address easily and then how many machines were in use at that time. A large business is a bit more anonymous. Also I'm pretty sure that NATing will still work with IPV6 even though it's largely unnecessary. With IPV6 you really wouldn't even need a router as a switch would do the trick, but I think most folks would still use one due to the fire walling abilities.

This is a rehash of old arguments from 2000’s. NAT isn’t about privacy or security. It just happens to be one of the side effects. NAT is about not having to re-address your entire network when you move providers. 

You DON’t NAT ipv6. If you need security get a real firewall :) Most larger companies (and probably what verizon is doing) is ipv6 RD. It’s a stateless tunnel. Your end device is only v6 and if you try to access a v4 device the provider does the necessary v6 -> v4 translation. If you go to a site that support v6 no translation is necessary and it “just works”.
