Another consequence of insisting on surnames is that those without a surname are forced to append say their father's name as a surname, with the result that their name now becomes twice as long. Each of the individual names (of the person and their father) was about as long as needed to be somewhat unique (some sort of universal "full name" length), but with the artificially added surname, the resulting length is now two times that. Quite annoying to spell out such long names on the phone for instance.
