On a more serious note: did you know that Prohibition occurred in America in part due to the efforts of women campaigners, who saw an end to alcohol as bringing about an end to domestic violence? Of course it didn't work—the root of gendered violence is the way that society creates situations where women are controlled and suborned by men: by their husbands, by their peers, by random strangers on the train.
I think it matters a LOT that this story was written by a woman, and presents a very particular fantasy of the "1,000 year old woman." This is in part because of the problem of reporting and retributive justice in real life: a wife who speaks up about an abusive husband admits her own fault in being unable to soothe him, to take care of his needs—because society places this responsibility on wives. A girl who speaks up about being molested is damaged goods, she's a ho. Furthermore, consider what happens to a wife whose husband is locked up: she loses her household income, she loses a man she once loved. It's a difficult situation.
The fantasy, then, is a source of retributive, restorative justice (she fixes the problem, but keeps the people around) which the female victim does NOT need to report to, does not even need to define the problem OUT LOUD to. The problem can be "solved" while going unspoken, without needing to involve a system of justice that has, traditionally, posed a great source of harm to female victims. The male perpetrator can be hurt to the point of feeling empathy, but not in such a way that causes problems for their victims. It's an intense form of wish fulfillment that comes from a place of equally intense hurt.
I think most girls have wished for something like this at least once in their life.
