No, I still don't get it. How is information about the private key in the ciphertext? It's great that one-time pad exists, but it's not really relevant in actual crypto code, right? The only actual reason I can think of is that symmetric crypto is easier to write and understand - you just mangle and xor some text back and forth, while in asymmetric crypto, you need to understand fairly complex algebra. But again, that's not that important if you use existing primitives, right?
