Indeed, individually your preferences can lead you to make choices that are different from the aggregate, and in so doing your choices marginally contribute to what emerges. Sort of like considering a market price too high, thus not buying. To be clear, that's distinct from actively attempting to broadly change what emerges, e.g., trying to "fix" the education system to no longer be structured for "signaling". To do that requires affecting the trillions of choices made by billions of people, and one way or another, that often requires violence or threats thereof.
