Ok, I see the point you were trying to make. But dust on the film during exposure is an issue with EVERY sheet film size not just 4x5. Spotting prints is a learned art.:D
Personally I think the concept of scanning film is absurd. Are there no good digital cameras on the market? The only logical reason to use film is to make a print on photographic paper. I guess some people don't like the look of photographic paper and to each his own. I know the glowing image on an iPhoney is more appealing to my youngest child.
