that's a very nice summary.
As mentioned the above image was shot handheld, so in this case at 1/500s because it was plain sunlight, but I have scanned plenty of images handheld at 1/125 or even 1/60 that easily showed detail over 4000ppi.
the point about grain is rather complex...
of course for pure object resolution, we'd want a sharp, very fine grained film and excellent lenses.
But to me the grain itself is a picture element on it's own that I really like, and most scanners show some aliasing if we enlarge a lot.
I scanned some 6x7 Portra800 negative for an exhibition, where the photographer printed 240cm wide, and the 11'000ppi scan made the grain look really nice and organic, while the Imacon 3200ppi scan he had done before looked edgy and pixelated.
I also scanned some 35mm Delta100 that was enlarged to 500cm width. It was shot handheld with an old Nikon lens and not terribly sharp by todays standard, but the detailed grain made the image look special even at this huge size, while a lower scan would have looked fuzzy and pixelated.
