You have to lay out the scenario in which anyone has to care, because the baseline case of "Elon Musk can look at a spreadsheet that has my personal information on it, along with every that of every other American citizen" is not threatening. Even if he is able to use ctrl+F on it to find stuff he cares about, he doesn't care about me, so I don't care yet. Maybe lay out a scenario in which he feeds the data into a computer which analyzes it and outputs subsets? But YOU'RE an American citizen, right? What concrete worries do YOU have about the use of YOUR data? Or are you implying that it is only MAGA retards who have cause for concern?
