That's a strange argument. Learning to do something is going from seeing it being done, to doing it. Seeing the raw material, seeing the end product (either in you mind or in the world) and being able to use the raw material in the right way to produce something useful. That is the hard bit - knowing how to control things to get the desired result.
All it takes to play the piano is to replicate the sounds of a tune you hear.
All it takes to paint a good observational painting is to smoosh some colours on a paper to match what you see.

It just doesn't work that way.
