See, Nash reasoned that at times when we were actually on a REAL gold standard (like when Newton pegged the british pound to gold in 1717) we had favorable economic times. But the problem is it is too singular. If an entity controlled the supply of gold or if technology changed dramatically then this would be unfavorable for such a peg. Then he thought about the possibility of using an international array of commodity prices, which could be arranged to be suitable. It is often thought (George Selgin made this mistake in dialogue with me) that Nash's proposal was for all nations to peg their currencies to such a basket.
But there is a political problem, because some commodities fall out of flavor (or into flavor) and so the basket would need to be adjusted, and this brings in the political component such a standard seeks to remove in the first place:

Here, evidently, politicians in control of the authority behind standards could corrupt the continuity of a good standard…
His proposal doesn't actual call for an ICPI (international commodity price index), he concieved that it could be done without it:

Then the limiting or “asymptotic” result of such an evolutionary trend would be in effect “ideal money” but this as a result achieved without the adoption of anything like an ICPI index as a basis for the standard of value.
It was just that this theoretical notion gave him the idea for the ultimately launched concept of (asymptotically) Ideal Money:

The ultimately launched concept of "Ideal Money" became possible when I conceived of a practical basis for a standardization of the comparison of the value of the currency with an appropriate standard or ideal. And the key to that was the idea of an ICPI or (international) "Industrial Consumption Price Index".
