I like the metaphor of a shipwrecked sailor clinging to a piece of flotsam in the cold water a mile from shore. He's losing body heat, and eventually hypothermia will set in and he will drown. But if he lets go and starts to swim for shore, he'll lose body heat even faster, use up his energy, and he probably won't make it. The "harm reduction" argument says that he should reduce his heat loss, and stay clinging to the flotsam. He's safe right now, while attempting to get to shore is difficult and dangerous.

Of course, by the time that the fallacy of that strategy becomes apparent (*gestures at current events*), he's too cold and weak to even attempt the swim.
