1. humans act speculatively to achieve goals for their "psychic profit" (subjective valuation).
2. humans rank goals by subjective preferences
3. according to preferences, humans rank their available means (tools/resources)
4. ranking of means and preferences yields unmeasurable "marginal utility"
5. ranking yields Riccardo's "comparative advantage" law.
6. on a market, individual subjective ranking turns into supply/demand curves aka "order book"
7. ppl need money to avoid combinatorian explosion in prices to compute.
8. historically, even most primitive tribes used some kind of money (seashells/stones/leaves) to do pricing.
9. money does not "move", but always sits in accounts/wallets
10. there is 1 unit of "money", everyone has fractions of it
11. hence, inflation of supply is equivalent (in long run) to taxation
12. inflation of supply does not recalc prices instantly => benefits those closer to source first
13. only humans act. Institutions (corps, govs) are imaginary labels.
