Yes, I think many people on this thread have been making the same point. 
  This is the basis of the Nash Equilibrium, from what I remember.

It doesn't seem to me Satoshi was classically trained in CS else maybe 
he/she/they might have referenced the Nash Equilibrium.  Looking at some 
of the other references, including a statistics book titled "An 
Introduction to Probability Theory and its Applications" from 1957 makes 
me think this Satoshi person was closer in training and practice to a 
mathematician.
