I think the argument is misguided, even if I agree with the principle: it is based in the effort one puts in and how it's similar to a sport.
I don't care whether my favorite author sweated for months facing a typewriter, of he effortlessly dictated the final form of the book in one sitting to a secretary while sipping mojitos.
I think my issue with AI has more to do with the signal it sends: reading takes effort, particularly literature, and I use the author's name as a proxy to judge whether to invest that effort myself. Nothing bad in selling dollar store crap, but it's bad to put 'Nike' on it.
Your individuality is what you sell as an author. I can get access to the LLM without you.

And you can read a car maintenance book. That doesn't mean you can fix your car now.
The author vouched the LLM output using their experience, that's what you get. Unless you are as experienced in their domain, it will take you time to figure out if the output of your LLM prompt is correct or non-sense.
