I think we fundamentally agree. But I would point out a subtle distinction: I believe TCP/IP and DNS provide an adequate building block for what needs to happen in a backwards-compatible progressive enhancement way. I distinguish this from IPv6 which - because of how we chose to implement it - has created a ton of chicken-egg issues with the incentives for adoption.
