I don't understand, "self hosted stadia" is just one of the myriad of services and tools that do literally that.

Steam has game streaming built in and works very well. Both Nvidia and AMD built this into their GPU drivers at one point or another (I think the AMD one was shut down?)

Those are just the solutions I accidentally have installed despite not using that functionality. You can even stream games from the steam deck!

Sony even has a system to let you stream your PS4 to your computer anywhere and play it. I think Microsoft built something similar for Xbox.
