Unless my understanding of how IPv6 is flawed, I don’t think your assertion is true in practice. One of the big benefits to IPv6 is that addresses are plentiful and fairly disposable. Getting a /48 block and configuring a router to assign from the block is pretty straightforward.
I’m aka unsure if IPv4 really gets you the privacy advantages you think it does. Your IP address is a data point, but the contents of your TCP/HTTP traffic, your browser JS runtime, and your ISP are typically the more reliable ways to identify you individually.

The downvotes are because you’re needlessly combative, preemptively complaining about downvotes.
You can nat all your ipv6 traffic behind a single IP if you want. Or a new IP for every connection.
Realistically though there's enough fingerprinting in browsers to track you regardless of your public IP and whether it's shared between every device in the house or if you dole out a routable ipv4 to every device.
CG-NAT gives more privacy benefits as you have more devices behind the same IP, but the other means of tracking still tend to work.
For me I just don't see the appeal of supporting both ipv4 and ipv6. It means a larger attack surface. Every year or two I move onto my ipv6 vlan and last a few hours before something doesn't work. I still don't see any benefit to me, the user.

"IPv6 just turned 30" - literally the first part of the post title.
The rest of the post is equally baffling, you are just clinging to a legacy bottleneck (NAT) that was never designed to be a security feature
It’s ok to understand something and disagree with it. It’s another to proudly wear ignorance on one’s sleeve. That’s never a good look.
There’s no way in which IPv6 is less private than IPv4. An ISP issues your house an IPv4 address and an IPv6 /48 network. Both of those can be subpoenaed equally. The privacy extensions work as advertised.
And in reality land, the big companies are the ones pushing for the upgrade because they’re the ones hardest hit by IPv4’s inherent limitations and increasing costs. Same rando in Tampa isn’t leading the charge because it doesn’t affect them much either way.
