I've only quickly read that. Kinda funny with reference to the Klingon Empire.

However this doesn't say anything about blank names. The closest it comes is point six.

6. People’s names fit within a certain defined amount of space.

But I believe that is talking about an upper limit rather than a lower limit.

If your first and last name (or any combination of however many names you have) is literally blank then how do you expect to function in society? Let alone modern society.

You'll end up with an alias (which is essentially nickname) that someone assigns you that will become your de facto name.... and now you have a name .
