Maybe I've been confused all these years, but I thought the Zone System was a methodology for defining the parameters and procedures regarding the equipment, materials, and processing to allow a photographer to produce a visual presentation of a concept regarding a given setting.

I'm quite sure many members here are scanning, be it negatives or prints.
The galleries which are full of images are evidence enough.
