Hook

Imagine you have ten dollars and you walk past a coffee shop and a bookstore. You walk into the bookstore. What did that choice tell us? Not that the book is 'worth' some objective number of utils, and not that you 'love books more than coffee' in some psychological sense. It tells us something narrower and more useful: at this moment, with these alternatives, you ranked the book above the coffee.

This is the entry point to Misesian economics. Value is not a quantity stored inside goods or inside people. It is an ordering — a scale — that an actor reveals through chosen action under scarcity.
