yes, but it's so common to expatriate nowadays, also for short periods. so it would be nice to have a digital ID thing to deal with different administrative stuff, in different countries...
However, ~1M goes back every year, so the affected people are more than the ones _currently_ living abroad.
Moreover, there are services that also intra-EU tourists can benefit from: - buying products >18 y.o. at automatic machines - simplifying buying drugs at pharmacies (we have EHIC, but it doesn't cover not-urgent care) - having fast track at airports without having an EU passport (in many countries people have an ID but not a passport) - easier lookup for police during random checks
