I think you need to take the tin foil hat off mate.
IPv4 in many places has RAN OUT. No more, zilch.
Most people can get a fully functioning CGNAT address and surf the IPv4 web just fine.
Most VPS providers will give you IPv4 and IPv6 just fine.
So really the only issue is for the 10-20% of people who need to host an online service, security camera or online game system that doesn't have a server or rendezvous service.
You can get IPv6 addresses. What you can't get, in many cases, is a static IPv6 prefix assignment.
CGNAT is not fine. Its problems are simply hidden from most people. ISPs have to have more equipment that's less reliable, increases latency, and is potentially a bandwidth bottleneck.
