I think your odd use of the exclamation mark is a great counter-example to your comment! After a long sentence with zero commas, here we have a punctuation mark! It doesn't exclaim, as in "Watch Out!" or "This is amazing!"! It's a questionable choice, it makes the reader think: why is this here? Is this writer casually throwing out punctuation that isn't needed?

That cognitive interruption, which I've kindly added multiple times to my first paragraph, is precisely what McCarthy says not to do in the very first bullet point of the article:

"Use minimalism to achieve clarity. While you are writing, ask yourself: is it possible to preserve my original message without that punctuation mark, that word, that sentence, that paragraph or that section? Remove extra words or commas whenever you can."
