Exactly. I randomly try to "upgrade" to ipv6 in my home once in a while and i always give up because I'd have to do the whole enterprisey setup for no good reason.
Edit:
Basically ipv6 is too complex and automated to hold your home network's whole configuration in your head without effort.
So the techies don't set it up at home unless they have a fetish for overcomplicated setups. They're not familiar with it so they don't push for it at work either.
Adoption is solely driven by ipv4 address space exhaustion. There is no "new toy!" feeling involved.
IMO, not having NAT is a "new toy". It allows end-to-end connectivity again. Any peer-to-peer apps work much better on IPv6, and if you're developing one then it's actually possible again.
You could try fd00::1, fd00::2, ... for short internal static addresses. You don't have to use a random prefix in that range - it's just policy (for good reasons that might not matter for a small network).
v4 networks commonly only get one IP for the whole network, and people use NAT with port forwarding to make inbound connections work. With this setup, an attacker only needs to scan the 65536 ports on the router to exhaustively enumerate every single publicly accessible server on your entire network, which is about 3 megabytes of traffic and takes approximately no seconds.
On v6, you don't use NAT and networks are /64. Finding every server requires scanning 65536 ports on all 2^64 IPs, which is about 72 billion petabytes of traffic. There are ways to prune this down somewhat, but however you do it the search space is still far larger.
If you want attackers to not know what's behind your router, you want v6.
That's what I meant. On v4, it's trivial to find every server that can be reached from the Internet, whether it was intentional or not. It's not so trivial on v6.
Note that V6 is easier to scan than some people assume. You don't have to scan all 2^128 addresses - you can look at provider address blocks in the registry, and make an assumption (or try it and see) what size block that provider assigns to each server, and then guess the server is ::1 or ::2 in each block. This isn't an exhaustive scan, but you'll find a lot of services this way anyway.
You can also e.g. monitor certificate transparency logs for hostnames. But the difference is that without NAT, knowing about one server on the network doesn't automatically give you the IP for every other accessible server on the same network. You have to actually try host IPs one by one instead of the router kindly filling that part in for you.
