I agree that too much friction is terrible.
But what I was saying, and the article seems to be implying, is that too little friction is terrible too.
Using Stable Diffusion is lower friction than sketching or painting. But the latter two are better.
The difference is that there is friction that leads to a good outcome, and friction that does not. Mixers with bread hooks are eliminating bad friction, whereas Stable Diffusion is removing good friction.
And in fact, there's actually more friction when using Stable Diffusion if you have an end in mind; trying to get it to output what you want is high in bad friction.
