The national identity is important, it's valuable, they exist, where they do exist, people who have them should be granted the means of political self-determination, normally in the form of an independent state. There are other cases sometimes through federal or devolved institutions within a larger unit. Citizenship in Western democracies is the modern equivalent of futile class privilege. It's an inherited status that greatly enhances one's life chances. To be born a citizen of a rich state in Europe or North America is like being born into the nobility in the Middle Ages. To be born a citizen of a poor country in Asia or Africa is like being born into the peasantry. Like feudal birthright privileges contemporary social arrangements not only grant great advantages of the base on the base of birth, but they entranced these advantages by legally restricting mobility. And if the feudal practice of protecting birthright privileges was wrong, what justifies the modern ones?
