Even if you have a system to determine it, it is still entirely make-believe.
A "system" serves solely to increase and sustain the total energetic commitment to that belief, rendering its signal correspondingly more expensive to revert to noise.
A massive stone pyramid is much more of a commitment to a set of social values represented by that monument, than is a speech given about those values.
But the speech, being infinitely lighter, can be carried everywhere, by anyone, and thus grows in strength with greater distance traveled, while even the largest monuments soon sink below the horizon.
All forms of money strike a tradeoff somewhere between these two semiotic extremes.
