NAT is the basic principle behind a VPN. You isolate your machines from the network completely. I mean, if you want them to have internet access, then you don’t need NAT, but if you want to isolate them and only have internal access, then why bother with IPv6 and setting up some weird firewall rules?
Uh, how? Fundamentally I disagree. I’d recommend reading the many other comments on this post for more context.

But I agree that NAT use cases are rare.
