That would work if every family member were okay with dumb terminals. Unfortunately, some of them require dedicated GPUs.

Routing thick black DP cables and bright blue USB throughout the house feels a lot less natural than just installing ethernet ports in each room. :(

I run my workstation PC with a dedicated GPU in a rack in the shed. I use Sunshine on the workstation and Moonlight on the client to access it. I can game like that, use blender for modelling, anything that needs more juice than my old laptop. It feels local. Even over WiFi I quite often forget I am on a remote machine. Moonlight runs on pretty much anything and everything too.
