Reading the comments so far, this question seems to necessarily raise another:

What is the best team size?

Let's say it's 3. (1 has too much risk and 10 has too much overhead.) Once your productivity needs exceed what 3 average developers can accomplish, if you place importance on team size, it makes sense to pay more for higher performance in order to avoid increasing the team size.

It's like paying to upgrade hardware on the network nodes you have (which exist to mitigate risk), rather than distributing work across more and more network nodes.
