do painters who use watercolors, acrylics, or oils argue like this?
Analogy fail. Watercolors, acrylics, and oils are comparible to B&W, color negative, color slide, or perhaps 35mm, medium format, and large format.

The real analogy would be arguing which is better, painting or photography. Or indeed, painting and digital imaging. There was a time when painting vs. photography was a real debate; thankfully everyone has gotten over it and now nobody asks painters why they just don't take a picture. Eventually, the same will happen with real photography and digital photography, and everyone will be better off.
