I think your statement about 99% of people it not being concern is true at any given snapshot of time, but not true across the lifetime of those 99% people. Case in point: Harvard student gets denied entry because of his friends' social media posts which were discovered upon searching his phone [https://techcrunch.com/2019/09/02/denied-entry-united-states...]. If you were to ask him, he would say he is part of 99% and has nothing to hide or be concerned about, and is probably true for most of his life, besides that period where his friend posted something on whatsapp and his phone being searched.
