Ah, the endowment effect. I don't understand why people worry about taxes so much. I mean, the way I see (you can add it to the list of mental models), there is a flow of money going through you. Some of the flows you can influence more, some of them less. There is no such thing as "your money". It's really arbitrary where we draw the line. For example, most people consider money they earned (before taxes) as theirs, while money spent on mortgage/rent as someone's else. In reality, they often have about the same practical ability to influence the amount in both flows.
