Summary

Currency = common denominator for market exchanges (literal, not metaphorical). Prices = ratios between subjective valuations. Essential functions: Fungible (units identical/interchangeable), widely accepted (reliable mediation), easily quantifiable (transparent transactions). Historical insight: Anthropology suggests money-like systems (debt/credit) may have predated barter, not evolved from it. Currency emerged as technology to quantify and communicate valuations, making incompatible exchanges feasible. Power of money: Salability (ease of conversion) + comparability (measuring opportunities) → not intrinsic value. Critical point: Currency doesn’t confer objective value—it maps subjective, agent-relative preferences onto common numerical scale. Universal translator expressing diverse valuations in standardized language. Reframing: Currency = mathematical/communicative tool, not inherent store of value. Demystifies money, highlighting facilitation role vs absolute measure. Conclusion: Value remains fundamentally subjective. Currency’s value resides in ability to express, coordinate, facilitate human desires and economic activities—not in itself.
