Please provide one concrete example, and explain how it does not exist in anarchy.
Well, I think we know that first we'd have to get you to agree that fines backed by threat of imprisonment is violence for many of them. However, consider something like Sarbanes Oxley where penalties include imprisonment (sorry, that's not violence in your book either, I'm sure) for certain types of transgression.
Please explain to me how there cannot be undesirable ramifications of not paying money to individuals or entities in an anarchic society.
