The proliferation of an identifier is driven by the use case. 100% of humans have a name because it is used to address them. >90% of humans have a mobile number because it lets you connect & communicate with people. ~60% of humans have an email address

Govts try to increase the number of people having national ids by making it compulsory for usage when you have use cases that involves them like international travel, voting, ration, etc.
