The person being cut up is not hurt, they gave their consent to be cut up. So why should third parties intervene? Of course if there is a shortage of dead bodies, medical students should be prioritized, but why not also open it to everyone. In fact, it is better IMO to have this regulated by universities as those will help with maximizing the learning, and ensure it happens in a respecting environment.
