Some of it is nostalgia sure you say film degrades after every run But to counter that argument every time a sound or image is made digital it degrades due to quantisation noise that is added. High bit rates help but it's just an artifact of the digital world

Quantization noise can be dithered below the threshold of perceptibility.

True and agree and but digital is still only ever a close approximation. The way the tech works is all it ever can be. It gets to the point where you can't notice but it's still a very good approximation

I will accept this only if you agree that analog is also only ever a close approximation.

The Nyquist limit is real and exists in the analog domain just as much as it does in the digital domain.
