There simply is not enough entropy for one name. Even in a small village. Hence why there are surnames (or equivalents, Jesus son of Joseph) Not a normalisation. True, surnames are used for hierarchical system hence why some people don't want to use them for instance. But websites aren't here to pander to you. They want to make $. The less entropy they have on you the better. It's not laziness and/or ignorance and/or unwillingness to learn.
