He wanted to go all out and maximise "company form". Same as optimizing your website for hundred of thousands of visitors even if you have only like one hundred visitors...
You get one chance at getting your company form right. Any other new chance costs a ton of money in restructuring. Software is malleable, companies are less so.

That’s the bare minimum consideration for a viable company structure.
