Why are you talking about hypotheticals and abstract "distrust" ? We're already being harmed by existing central ID systems - social security numbers and drivers license numbers - with little hope for reform in sight. If there were something like the GDPR that prohibited companies from nonconsensually demanding, storing, or using these identifiers for anything but their bona fide governmental functions, then it might make sense to talk about adding a new system. But until the government is capable of reigning in abuse of the existing systems, any new identification system would inevitably be a gift to the surveillance companies.
