This is a common error, it doesn't follow that because you don't own yourself as property, that you can be morally permissibly killed or raped. For instance, it might be morally wrong to rape you because it has bad consequences, i.e. suffering. There are many other moral frameworks which explain why rape is wrong other than deontological self-ownership. That doesn't mean it isn't a valid theory, just that this is a bad argument for it.
