Now with a 16-bit device, here's what we get with a two-stop under-exposure.

Now on the basis that light generates electrons proportionately, then it's
clear to me that the 16-bit device is a clear winner with 8 f-stops more
being resolved!
This the fundamental flaw in your argument, 16 bit does not record 8 f-stops more, the bit depth has nothing to do with the range of stops that a device (or film ) can record. All it means is that range no matter what it is 8, 10 or only 3 stops is broken up into 16 steps. Thus 16 bit gives a smoother representation from black to white. Imagine going from ground floor to 1st floor. First with 8 steps, then the same height with 16 steps, obviously the 16steps will each be smaller but in total cover the same distance
