There should be a name for the fallacy of expecting people to "vote" with their dollars on every single issue all of the time.

It's like the opposite mistake that communists make. They expect a single centralized decision maker to balance all considerations to set a price, which is inevitably ineffective.

This vote with your dollar argument expects every individual to balance all considerations to set their own personal price. There is an assumption of information symmetry and unlimited ability to analyze on the part of the individuals behind the vote with your feet argument that is just not remotely true.
