This chapter argues that in economics, property itself is more important than property rights. Property shapes the rules we follow, not the other way around. The common idea of property rights as external controls doesn't capture the full picture. Instead, our understanding of property is rooted in our minds and society's values. The book suggests that property influences how we view rules and society's moral structure. This different perspective challenges the typical concept of property rights as buildings blocks. The focus shifts to how property shapes our expectations and guides our behavior, making property the core of economic principles.
