This is just made up shit though. None of what you are stating is backed by any sources.

>Per dozens of engineers at SpaceX...the biography from Isaacson contains numerous exaggerations and outright fabrications.

Which ones, specifically?

>the sense that he was presented multiple options by the engineers and designers and got to pick which one they went with.

Even if this were the only level of involvement, do you realize how important these are? Do you know how it would have worked out for the company if they focused on payload instead of reusability?
