GUID following something like rfc4122 would be definitely better than current national id implementations that tend leak personal information. I have two national ids (from two different countries). Both of them leak my birth date and the second one also leaks my gender and even birth place. The main question is - who should be such authority that would actually provide such identifiers that are guaranteed to be globally unique without collisions.
