Only in a very grossly analogous sense can we claim that de-mosaicing is the same as introducing external data into the scene. It's not the same thing at all. The limits of what can be resolved for a given sensor and optical system are understood. When we know where the system limits are, we can use calculations to help us see just a little better, to enhance or visualize the recorded data/"graph". In so doing we have a good understanding visual phenomena recorded from the natural world vs artifacts introduced by some limit of the system and/or overprocessing of it's recorded data. Think of moire patterns, LoCAs, shutter speed effects like wobble, and others.

There's a world of difference between doing best guesses (mathematical computations) based on what we caught in the frame, and adding supplemental external data to the frame.
