This is a phenomenally good comment. You take the core concept, homomorphic, which is possibly opaque to someone not skilled in the art (of encryption algorithms) and explain the main advantage of this approach using a real-world example that is both complete for the purpose of illustration and also relevant for 'why should I care'. Encryption has always been something that I care about as a user, but your comment indicates that it might be a practical application for the group theory that I've been reading up on as a hobby. Bravo, good parent.
