Your rant doesn't make sense. The solution is already known and you mention it: ULA. It's not a compromise. You don't need to bite the bullet. Just use it. It's designed for this use case. Fixed IP address for every single device.
If I use a global unicast prefix, the IPs I see on my devices are their real honest to goodness routable IP. That is great!
But I can’t use that IP in any configuration because it will change. That’s not so great.
So I have to compromise by not using the routable IP in places where I need to put the address in a config file.
Nobody wants ULA. ULA is a solution for the fact that your prefix will change, which I wish didn’t happen.
You can say it’s unreasonable to expect a stable prefix (and we could argue about that all day) but don’t pretend it wouldn’t be massively beneficial if I could rely on one. It is absolutely a compromise. A necessary one? Yes. A reasonably simple solution to implement? Yes. But it’s still a compromise.
Well as someone else mentioned, do you want your devices to have no address when your internet connection goes down? A global IP is also a compromise unless you have your own ASN.

Homie likes to pretend to overcomplicate things. Check the comment history, this rant isn't new.
And yeah, folks need to understand that ULA addresses are functionally equivalent to RFC 1918 addresses, and ask themselves why they'd expect an ISP who charges extra for an unchanging globally-routable IPv4 address to give you an unchanging globally-routable IPv6 prefix for free.
id assume those unchanging ipv4 addresses are not shared and natted with other customs and thus charging for them makes sense as you're consuming a limited resource they are paying for.
That's not the same for not changing an ipv6 address
> id assume those unchanging ipv4 addresses are not shared and natted with other customs...
Over the last several decades of me having residential Internet service from a variety of ISPs here in the US, I've never had an IPv4 address that was not globally-accessible. Relatedly, I've never had a guaranteed-static IPv4 address, but I COULD get one if I paid the ISP additional money.
I understand that in other regions of the world NOT being behind CGN is not guaranteed.
> That's not the same for not changing an ipv6 address
Hopefully you now understand the context in which I made my remarks. In the world that I (and many other folks) live in, I get one globally-accessible, but definitely-not-static IPv4 address.
