I think the "nothing to hide" argument is made for a different reason.
People are unafraid of the government knowing certain things because they believe it will not have any real repercussions for them. The NSA knowing your search history is no big deal (as long as you're not looking for anything illegal), but your church knowing your search history would absolutely be a big deal.
When someone said "I got nothing to hide" I always took it to mean "I will tell the nazis when they come which house to look in".
It's good to know in advance who they are.

A very famous quote: "Conservatism consists of exactly one proposition: There must be in-groups whom the law protects but does not bind, alongside out-groups whom the law binds but does not protect."
Many people - particularly white people, but let's not ignore that a bunch of Black and Latino folks are/have been Trump supporters - believe that they are part of the in-group. And inevitably, they find out that the government doesn't care, as evidenced by ICE and their infamous quota of 3000 arrests a day... which has hit a ton of these people, memefied as "leopards ate my face".

Until someone at or above the TSA decides they don't like you. And then they use your search history to blackmail you. Because lots of people search for things that wouldn't be comfortable being public. Or search for things that could easily be taken out of context. Especially when that out of context makes it seem like they might be planning something illegal
Heck, there's lots of times where people mention a term / name for something on the internet; and, even though that thing is benign, the _name/term_ for it is not. It's common for people to note that they're not going to search for that term to learn more about it, because it will look bad or the results will include things they don't want to see.
