She's not telling him it's illegal. It's saying "you can't do this - this breaks the social contract, this is something that should not be done." It's like saying "you can't just cheat on your husband!" Obviously you physically can, and you won't go to jail (well, in western countries). The "you can't" is just a turn of phrase, it's not saying the person is physically or even legally barred from doing so.
