The assault example is completely different - having a bunch of strangers view a video of you being beat up doesn't really impact your privacy. Having a bunch of strangers watch a woman engage in intercourse, especially if nonconsensial, is an egregious violation of her privacy - by having people watch the video, you make the crime much worse, which simply isn't the case with assault. Completely different. And knowing that if a woman reports it, she'll have to have strangers watch it will absolutely chill reporting so many women won't report it. That's not true with assault. It's really difficult to overstate how awful it would be for the victim to have this video watched by a bunch of random administrative strangers.
In a non-criminal, non-civil setting like this, it's important to balance the rights of the accused against the rights of the victim not to have the system further abuse her, and not to turn the system into an accomplice in the crime. These issues don't exist with assault. So that analogy really doesn't work.
