That’s a path directly into a money burning machine that goes nowhere. This has been tried so many times by far larger companies, academics, and research labs but it never works (see all proposals for things like content address networking, etc). You either get zero adoption or you just run it on IPv4/6 anyway and you give up most of the problems.

IPv6 is still struggling to kill IPv4 20 years after support existing in operating systems and routers. That’s a protocol with a clear upside, somewhat socket compatible, and was backed by the IETF and hundreds of networking companies.

But even today it’s struggling and no company got rich on IPv6.
