That's why you need his home address.īut the home address itself isn't enough on its own, either. While this would be enough to get your package to John, you can't just tell the post office to send it to "John Smith, son of Edward, son of George, son of." Even though it uniquely identifies him, it'd be a pain for the post office to find him.
However, what if we incorporated his ancestry (i.e., his "manufacturer") into his name? If we did that, he'd be called "John Smith, son of Edward, son of George, son of." Go far back enough, and it becomes unique. John's name isn't unique enough as an identifier, so we can't just send a package labeled "John Smith" and expect it to arrive. Let's say you want to send a package to your good friend John Smith.
