I spent a week without IPv4 to understand IPv6 transition mechanisms

Yeah, there are a lot of situations where NAT is actually preferable. Not everyone is going to need inbound ports, and the stability you get by having internal addresses is a feature, not a bug

Tie all your network config to your IP space provided by your ISP and now suddenly it's a pain to migrate to a different ISP

Or, if you want to carry your own IP space, now you have the administrative overhead of managing that (and, now you have to go with higher-end business internet service that may be more than you need, just to support bringing your own IPs)

I feel like if you want a robust ID for your machines, using DNS instead of hardcoded IP adresses is a better idea. That way you can move services from edge to cloud and vice versa with a single nameserver update, instead of having to do so on every single edge.

Or, if you want to keep things local, run a lightweight nameserver on your LAN to resolve .home or .lan domains. Much nicer to type fridge.home in your browser than 192.168.1.57 or some such.
