Me: This works with 2 people.
You: Yes, look, here they do it with 22 people.
2 of them are described as "Lead" which is contrary to the point you want to make: "You Weren't Meant to Have a Boss."
Additionally the problem of putting someone in space is different from putting someone on the moon and back again.
For example right now a duo are preparing to do a manned space flight, which would have been unthinkable 30 years ago.
