You're abstracting again. The whole thing hinges on where you sit with regard to class struggle. You seem to want to define "coercion" from some god like perspective completely abstracted from real life.
No. I want to look at real uses of the word "coercion". It doesn't have a class struggle meaning. Violence doesn't have a class struggle meaning. Just because you don't look at something in the abstract doesn't mean that you look at it politically.
