In that case it’s simply a question of what you value most, your biometric privacy or the ability to have an international travel permit. It’s a choice; neither option is forced on anyone.
Well, to be fair, a lot of people probably do support the idea that their own country checks the documents of people who enter and exit through their borders, and are maybe glad that the country they are visiting is similarly careful, but in principle, someone might want to emigrate to Antarctica, and never return to their country of birth, and for them it would be an unnecessary burden to have to apply for a passport.
I made the deliberate decision to travel and see different cultures.
But to be frank, I was more or less forced, because I was traveling with my parents ;-)
