It's probably because this law was established by the efforts of second wave feminism (1960s-1980s). Those other ones are far older and more fundamental social behavior laws that aren't enforced nearly as much. I'm hypothesizing that second wave feminism is an issue dear to the current generation of judges and prosecutors, since they were young then, which is why it gains far more traction in the American court of law. Even reality TV Judge Judy references second wave feminism in some of her judgments. https://en.wikipedia.org/wiki/Second-wave_feminism https://en.wikipedia.org/wiki/Second-wave_feminism
