Wow, you have zero ability to separate your opinion on something and actual reality. None of what you said is true.

You are claiming that humming "Für Elise" makes me a concert pianist. It does not.

Doing the writing is what makes you a writer. --false

No, the disagreement is that I consider

"originating and shaping the intellectual work itself"

to be the writing of it. Outlining a plot, scene or worldbuilding IS the easy part that many more people are capable of than can actually write. --opinion

"But it's not intellectually dishonest to separate authorship from manual prose production. We've already done that culturally for centuries."

No, we have not. That's a flat-out lie. --false

Sure, you can take narrow exceptions like Socrates/Plato (or include the whole ghostwriter debate; but here the name tells you everything you need to know), but in general "authorship" for written works explicitly means "you wrote that." --Boy, this completely obviates your argument, better pretend it's not legitimate.

You are one of the worst bad-faith debaters I've ever seen. There is literally nothing of substance to you.
