Why do you need all that? I have my work laptop sitting at the back of my desk. Most monitors have two inputs. I’ve got an older 1080 with HMDI+DVI and a newer 1440p with DP/2xHDMI.
So I have the laptop in HDMI on both screens (it needed a USBC to HDMI cable for one of the outputs), and a simple USB3 switch for the mouse+keyboard.
So when I’m working I fire up the laptop, switch the USB over to that and swap the screens to the HDMI inputs. When I’m done working I can fire up the desktop, swap inputs and USB and in seconds I’m switched over.
I’ve been doing it this way for years and years now.
That’s normally what I do, the problem is the context for me, I sometimes prefer just sitting across the room with a laptop so I’m in a slightly different environment
It can help draw a line I’d agree, but I’ve gotten used to it now I think. I used to have it worse. I operated out of the bedroom for the first few years I was remote and that wasn’t good at all. The new house had a bedroom that was really too small to be a bedroom. So it became an office room.
