Interesting idea, but the point of uuid is to not be centralised, otherwise you'd just use a serial number.

So if we assume everyone is born in a room with an address everyone could have a uuid like xxxx-yyyy-zzzz where xxxx is the postcode/zip code of the address, yyyy is the room number (only needs to be unique at the address) and zzzz is the time (only needs to be unique in the room, so local time is fine). This is similar to the uuid v1 scheme.
