> Every person on Earth, using their country's Unique Identifier credentials what about people in countries which don't issue "Unique Identifier credentials"; noting the limitations on the Social Security Number in the US, which was given as the first example?

I know multiple people who have 4 or more government issued "unique identifier credentials" Note: I suspect goobergoo's post has a high level of sarcasm; my reply is a criticism of META not of the post.
