the word effectively is holding a magical position in your argument
It is the alchemy of lead into gold. A photograph for representation does not equate the crafting of representation b/c those two are not the same process.
Please do not try to equate different things by using alchemy and magical words like effectively. It is lazy and wrong.
Also writing and copying since they both have similar craft seem to work for your argument as well, but they do not translate metaphorically with your understanding of photo and painting. that is just obvious.
Though your last point, disconnected from the prior two wrong points, is fine since it mostly an opinion. And one that I agree with, kind of a rut we are in with just textural exploration.
But that is the direction of art to explore just color or shape. We are exploring our basic infantile constructed aspect of art and looking if there is anything there.
