So IPv6 is expensive, but NAT is not? What makes IPv6 so expensive?

I've not said NAT is not expensive. But it's less expensive then NAT+IPv6.

That's not my experience, anyway.

You mean: you have case study where ISP implemented NAT64 and saved money (in comparison to plain old NAT)? Hard to believe, but I'll be interested to hear more about your story.

How do ISPs respond when customers complain they can't reach IPv6-only sites? Sure, this won't happen for a while, but eventually it will.

I think they'll tell you these sites are broken and you should ask for them to be fixed. If you'll press they'll admit that yes, it may be fixed on their said and that they are "investigating it". The answer is the same for the last 10 years, so I doubt it'll change any time soon.
