I don't know what your definition of a "smart passport" is, but the ones we have in the EU are pretty awesome. NFC chip on them that can be scanned to provide the biometric data - use cases are automatic identity checks at airports with passport+smart camera that compares, and the same via a government provided app where you take a video of your face, scan the chip, and the app compares them. Both are great, secure ( much more so that sending a scanned copy of your passport/ID card), practical, and can and are done with privacy in mind ( as much as privacy is possible for the airport scenario).
I don't understand people like you. Making people's lives easier is one of the main points of tech. All such advances on that particular level should be done with old school backups for people who can't use the tech (old, disabled, etc.) but those should be the exceptions. If almost everyone can use a system which is more secure, takes less time, and requires less money/time to run, why not? Why not make it the default? Why not make life easier for 90%+ of the adult population?
