yes but Nash's point relies on the observation that the process of picking suitable "goods" (or services, or utilities, or stable costs etc.) can be politically corruptible as well. So theoretically the ideal standard lies here, but you have to solve the problem of political power and corruption as well. Nash's points this out, and then proceeds to propose a different view that alludes to a creative solution.
