> A lot of people feel they have nothing to hide and don’t feel strongly one way or the other on privacy

People think that, but once you tell them they will lose their drivers license since they chatted to their spouse about bad eyesight they bark differently. Or shrug it off with "that will never happen to me" and you can start the "and then they came for the [next group], but I did nothing" line of talk.

Everyone has something to hide, they might just not know yet what it is but they will when the option to hide it has gone away. There is a reason my country stopped recording religion since 1946 in the citizen records, it was fine to do so decades before.
