Think about it this way: if a provider wants to charge on a per-/128 basis, and the user only wants to pay the provider once but connect multiple devices, then the only way to do that is IPv4-style NAT. As I noted earlier, in this model (almost) everybody is worse off, but it's not clear that there's a way to avoid that happening.</div>
