I agree with you but I think the point pretty much explains itself. Team play and willingness to produce the best your customer wants (and not the 3-star best) is exponentially efficient when you start to grow a team.

However I wouldn't say the same things when it comes to the first version of your core team. Every "10x" developer can work with 3 people but are they still "10x-effective" (do they even exist?...) when incorporated in an existing 5/6/7 people team? I don't believe so.
