It may not matter in the developed world where this cost doesn't matter because infrastructure is cheap. There are still limits to how much this can scale as a solution no? For a Country like India, surely this cost will matter especially for it's poorest citizens. The limits of this infinite scaling NAT will matter. That and the cost of an IP which I imagine will inflate much higher than $20 an address. It's 2020, why isn't this a priority on the roadmap. I think it would have a much more meaningful impact to those that need it.
