> Connectivity providers should allow that. Most home routers don't get a static IP, or even a globally routable IPv4 at all. Or even a stable IPv6.

At least we still have DDNS which solves the static IP problem. I've been using it for at least 10-15 years and my home network has always been resolvable over DNS. I guess I'm lucky that I've always had an ISP that handed out publicly routable IPv4 addresses. I think if I joined an ISP where I got some internal node on the ISP's 10.x.x.x network, I'd immediately cancel my service.

Both or those are solved by having a tunnel and a cache that is hosted in the cloud. Something like tailscale or cloudflare provides this pretty much out of the box, but wireguard + nginx on a cheap VPS would accomplish much the same if you are serious about avoiding the big guys.
