> v4 addresses become ever more expensive and the cost of CG-NAT deployments continue to climb.
But IPv6 is not an alternative to CGNAT. If you don't provide either a routable IPv4 or CGNAT, your customers will ask their money back because their internet is broken. The fact that you provide IPv6 or not is completely irrelevant to the vast majority of consumers or businesses.
This here is the major failure of IPv6 design, confusing what "the internet as a whole and the ISP community" need, with the individual incentives that make a single ISP provide for those needs.
