So the question becomes "How would devilish powers work in 21st Century America" and the answer seems to be "A contract is valid until it isn't". In the real world, a landlord can put a clause into a contract making the tenant responsible for normal wear and tear. That's not legal, but that doesn't mean you don't have to pay your rent on time. So HW derives power from a contract until someone with the authority to do so rules it invalid. It would be interesting if Arianna had, e.g., only canceled clauses 2, 7, and 18 (i.e., part but not all of the contract). What happens to her powers? Do they diminish by 1/6?
