 Why prefer norm-dependence to norm-independence? Often, the move to norm-dependence is motivated by familiar worries about over-generalization. The world may be full of uncontrolled powers of choice interference, but it is less common for one agent to regard someone else as a source of binding norms. I may have an uncontrolled power to interfere with your choices whenever I can take the last seat in a café before you can get to it; this obviously has nothing to do with any kind of authority over you. The latter power seems less ubiquitous and more serious.
