No, you haven't spent a fair time. Nash is nearly 90, and has been lecturing on the topic of "Ideal Money" for 20 years. He had his revelation in nearly 1960 on what would become "ideal money".
Szabo read Nash, and Krawisz read Szabo.
I can read Krawisz and then avoid reinventing all the wheels so that I have time to focus on the few wheels I do want to reinvent.
