There's a big difference between these scenarios.
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.
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.
It's good to know in advance who they are.
Do any of these actually prompt someone to reconsider their position? They strike me as more of argument through being annoying than a good-faith attempt to connect with the other side.
“Ultimately, arguing that you don't care about the right to privacy because you have nothing to hide is no different than saying you don't care about free speech because you have nothing to say.”Huh? You can’t imagine boring people as a “good faith social individual”?
'Saying' is an example of 'doing', and the moderation to speech happens after the fact, including (yes) in USA. Consider the case of a person yelling fire or 'he's got a gun!' when there is none, or a death threat.
If you're talking directly to one person and trying to convince them, without an audience, there are likely different tactics that might work, but even then, some of the same approach might help, just couched more politely. "You don't actually mean that; do you want a camera in your bedroom with a direct feed to the police? What do you actually mean, here? What are you trying to solve?"
Option A: "Yes!", which tells you you're probably talking to someone who cares more about not admitting they're wrong than thinking about what they're saying.
Option B: "Well, no, but...", and now you're having a discussion.
Generally speaking, people who say things like "if you have nothing to hide" either (charitably) haven't thought about it very much and are vaguely wanting to be "strict on crime" without thought for the consequences because they can't imagine it affecting them, or (uncharitably) have attitudes about what they consider "shameful" and they really mean "you shouldn't do things that I think you should feel shame about".
That's privacy in a crowd and even if they couldn't describe it, people do recognize it.
What you are proposing in every single one of these, is violating that in an overt and disruptive way - i.e.
> "Let's send your mom all your text messages."
Do I have anything in particular to hide in my text messages, of truly disastrous proportions? No. But would it feel intrusive for a known person who I have to interact with to get to scrutinize and comment on all those interactions? Yes. In much the same way that if someone on the table over starts commenting on my conversation in a coffee-shop, I'd suddenly not much want to have one there.
Which is very, very different from any notion of some amorphous entity somewhere having my data, or even it being looked at by a specific person I don't know, won't interact with, and will never be aware personally exists. Far less so if the only viewers are algorithms aggregating statistics.
E.g. "Can we put a camera in your bathroom?"
Very few people are arguing that nudity or bathroom use shouldn't be private, and they are not going to understand what this has to do with their argument that the NSA should be allowed to see Google searches to fight terrorism or whatever.
Privacy arguments are about who should have access to what information. For example, I'm fine with Google seeing my Google searches, but not the government monitoring them.
But on the internet we often do this thing where we take the weakest version or a distorted version of an opposing side's argument and ridicule that. It's not quite strawmanning because we never specified who we're arguing against, and surely we can imagine someone, somewhere on the internet has the ridiculous viewpoint. But it's not a common viewpoint (that, for example, we shouldn't have privacy in the bathroom). Doing this only gets us pats on the back from those who already agree with us and deludes us about our opponent's position.
Some retorts for people swayed by that argument:
"Can we put a camera in your bathroom?"
"Let's send your mom all your text messages."
"Ain't nothin' in my pockets, but I'd rather you didn't check."
"Shall we live-stream your next doctor's appointment?"
"May I watch you enter your PIN at the ATM?"
"How about you post your credit card number on reddit?"
"Care to read your high-school diary on open mic night?"
