"Under duress" seems to be a somewhat fuzzy classification, but most of these necessities have either very low costs for switching to another counterparty (if I don't like one grocer's offer, there are plenty of others around I can go to instead on the spot) or some limitation on what they can require (e.g., no kicking a tenant out without a month's notice). At-will employment seems to be the odd one out here, in that switching to a new job normally takes quite a bit of time and hassle.
