Even cheap consumer hardware supports ipv6. There are significant financial incentives to continue the capitalism of ipv4 addresses. Like NFT's - an artificially limited capital. To create more addresses means more competition, loss of capital. Therefore they will spend billions on continually reworking internal IPV4 than going for the proper solution.

You obviously have never been on the backend of a big enterprise deployment.

The world is bigger than your apartment.

I worked in a company where we had network equipment all over the world.

Often IPv6 and IPv4 paths were entirely different and latency on IPv6 was much bigger, so we had to measure latency between nodes on both. Also, sometimes IPv4 was a symmetrical, but IPv6 wasn't. As a result, we had to buy tons of IPv4 addresses.

Our control plane was on IPv6, but data-plane had to be on both.
