Following incentives is not the same as a marketplace. Marketplaces have a number of additional assumptions. * Items are capable of being traded. * The items being traded are unchanged by the process of assigning a numeric value. * Abstract concepts such as “risk” and “investment” are best measured in the same numeric values as are used for concrete items. Adding to that, even if I were to accept the reasoning that following incentives is equivalent to being in a marketplace, your statement that “In all situations, the human being follows incentives .” is simply untrue. It ignores the existence of self-sacrifice (e.g. a soldier sacrificing themself to save comrades), the existence of self-harm (e.g. Jonestown), and the distinction between incentives and perceived incentives (e.g. also Jonestown).
