It's a provocative title, but I think this section better captures his scope of argument - "Collaboration-as-ideology has made ownership and responsibility feel antisocial, which is a hell of a thing, given that ownership is the only mechanism that gets anything across the finish line.", as well as "But there’s a huge difference between communication and collaboration as infrastructure to support individual, high-agency ownership, and communication and collaboration as the primary activity of an organisation".

I think the author has identified that most organizations both fail at effective collaboration, and also use collaboration to paper over their failures.

I think the author maybe over-corrects by leaning on the idea that "only small teams actually get stuff done", and honestly I don't think anyone should be using SLA Marshall/Men Against Fire as an analogy for like... office work (if nothing else, even if you take his words at face value, then the percentage of US infantry who fired their rifles went up from 15-25% in WW2 to ~50% in Korea due to training improvements), but I can get behind the idea that a lot of organizations are setup to diffuse responsibility.

I also do think it's interesting to think about building the Pyramids. For the vast majority of people involved... I don't think modern audiences would call their work relationship or style "collaborative". Usually we use "collaborative" in opposition (at different times) to "working alone", "working with strict boundaries", and "being highly directed in what to do". Being on a work gang, or even being a team foreman is very much "no working alone", but those were also likely highly directed jobs (you must bring this specific stone to this specific location by this time) with strict boundaries.
