You probably don't see it directly, but IPv4 IP addresses are getting expensive - AWS recently started to charge for their use. Cloud providers are sucking them up. If you're in the developed world, you may not see it, but many ISPs, especially in Asia and Africa, are relying on multiple levels of NAT to serve customers - you often literally can't connect to home if you need or want to. It also breaks some protocols in ways you can't get around depending on how said ISPs deal with NAT (eg you pretty much can't use IPSEC VPNs and some other protocols when you're getting NAT'd 2+ times; BitTorrent had issues in this environment, too). Because ISPs doing NAT requires state-tracking, this can cause performance issues in some cases. Some ISPs also use this as an excuse to force you to use their DNS infra that they can then sell onwards (though this can now be mitigated by DNS over HTTPS). There are some benefits here, though. CGNAT means my phone isn't exposed directly to the big bad internet and I won't be bankrupted by a DDOS attack, but there are other, better ways to deal with that. Again, I do get where you're coming from. But we do need to move on from IPv4; IPv6 is the only real alternative, warts and all.
