This doesn't go far enough. The institution of dueling should be brought back as a legally valid contractual arrangement. It may be morbid, but if two people really deem the situation to be so critical, and provided that they duel in an isolated location, it could be doable.
Not that it should necessarily be encouraged. But to prohibit it entirely seems counterproductive, like the hilariously unenforceable prohibitions against suicide (unless you survive, making you wish you had succeeded once facing the legal consequences).
