Utility is ordinal, not cardinal, making it impossible to compare or aggregate preferences coercively.

PREFERENCES ARE LIKE BITCOIN: SOVEREIGN AND UNQUANTIFIABLE.
Bitcoin is money, the most quantifiable good.
🤔 not sure about this one. Isn't a price a comparison of utility across aggregates?
Price is a quantity of money, but price is never the exact value of the individual, it has to be lower than the good traded, otherwise trade wouldn't happen.
That's why property rights and trade are so important, it gives a cardinal valuation with which we can do math and accounting, whereas this is impossible with subjective valueation alone.
Yesterday it didn't make sense ; today it does. Brains really are like computers - you just turn them off and back on and stuff works.
