Yeah it feels like the author is strawmanning what "I have writers block" means. It's not that they've forgotten every word in the language. They have thoughts. Those thoughts are probably like "I hate this writers block, ugh what to say, what to write, I'm having block...". Doesn't matter if they wrote that out, no one would want to read it. And we all know there are too many "meta" pieces out there about the author's struggles with writer's block - please don't subject us to another one!
