It doesn't. Realist game theory ignores issues like morality. Unfortunately this forum is primarily liberal, in both the classical sense and the international relations sense, so you are going to be heavily down voted for questioning the status quo.

I don't think they are questioning the status quo tho. They are essentially asking "why be motivated by anything at all". Inevitably, you work in support of an economy, and therefore a nation, so at some point you have to choose which.
