It's no problem if the villagers stop getting her help, they were the ones who were dumb enough to chase off the golden goose. But Stephenie is being pretty dumb. She clearly wants the manor itself, so the obvious solution after her silly mortage scheme fell through was to just build them a new hospital. If she created an even nicer place for the MC to practise medicine, rather than being a cartoon villian Stephenie would be praised to the hills.
