I would say that it's not just useful, it should be a basic right. In my case as an EU citizen, Swedish citizenship gives me little more than I already have (voting rights, easier to get passport), but for those who come from outside the EU, citizenship is a question that affects all their life and of their family.

Just go and ask any immigrant friend if you have any. Just stop conflating citizenship with any sort of identity or morality, there is nothing like that.
