If every doctor has a means of removing it, the same means will be available to the rapist. I'm guessing it will promote a false confidence and assuming that the guy is a serial rapist out with the intent, he would simple proceed the dick with a stick, dildo, pickle - etc and feel even a little better about the experience. Since rape is suppose to be about domination - I'm guessing that it will be no difference in spraying him with mace as far as the abuse that will follow resisting him.
I really think it is more symbolic for women than it is practical.
