I’ve found that reminding folks who use the “you have nothing to hide" argument often quickly change their mind if you just remind them the political party they don’t like could use it against them

This worked surprisingly well and without fail for the conservative side of my family. The instant I reminded them who was president at the time (Obama) all of them changed their mind

I don’t love this strategy. It leans into fear mongering a bit much, but if none of the other very helpful rhetorical techniques folks have shared here don’t work. This one has some staying power.

Look at human history. We absolutely ought to fear power and those who wield it.

As I mentioned in a recent comment:

The balance between privacy and the authority is just that. We outsourced the rule of law to the state in order to have a fair and just society. Ipso facto the government should be fair and just to have the right to invade some amount of privacy in order to keep a society free, fair and just.

That’s why the judicial branch exist: to see if what the government (or anyone) did was playing by the rules. Which brings us back to politics being a danger to a society if people vote in unjust or unfair people.
