Yes, I would guess that this is what would happen when you kill off all the pure criminals. However, new ones should be born all the time along with the standard reproduction rate, and there should be some sort of threshold where an individual who is both MIR and CWC capable will opt for MIR behavior against a pure CWC individual under certain situations. For example, take a wealthy CWC and a poor MIR/CWC. A poor MIR/CWC is likely to profit much more by victimizing a wealthy CWC than by cooperating with it. Also, a wealthy MIR/CWC may try to get away with practicing MIR on a poor CWC.

Sure. A 3D video game which combines Duke Nuke'em with some pure market cooperation capability.

A group of CWC/MIR's could conceivably cooperate to practice MIR on a much more powerful MIR... the pure CWC's could buy protection policies from the CWC/MIRs.
Keep me posted.
