A couple ideas:

If you don't like privacy then you don't need curtains in your house.

Ask them to unlock their phone and hand it to you. Most people will balk.

One thing to think about is that some people don't mind losing their privacy to the government or a corporation but they do care about losing it to real humans that know them. As an example, if a husband is cheating on his wife he doesn't care if the NSA or Big Tech knows about it because they (most likely) won't do anything negative with that information. But he would want to keep that information from people he knows because they may use it against him and will definitely treat him differently by having that knowledge.

Food for thought.

Not uncommon at all to have no curtains. Portion of those that do, might use them for other purposes too (glare, light etc).

People will balk at giving a random friend their device but probably will be perfectly okay handing it over unsecured to a repair shop. People will be unwilling to show many body parts to a friend but likely perfectly fine showing them to a doctor.

That I do not want to show something to you specifically, doesn't mean I'm hiding something from you. If you ask me to give you my browsing history I may or may not. Depends on the reason. If it gets leaked to everybody I will be rather unfazed. But if you call me to tell me you're carefully examining the leak at this very moment, I will still feel weird about it.

Another example. The nearby grocery store knows what food I'm getting every other day. Would I like this information broadcast to friends and family in real time? No, would feel awkward. Will I go crazy if the list for the last 2 years gets leaked in an instant? Not at all.

I find the curtains argument stupid. They look lovely, are sound-absorbing, and I'm not too fond of black windows at night, which mirror everything.

Other than that, good points!

Another alternative to curtains are blinds which also help to block your reflection at night. However they’re not good at absorbing sound so you are probably right to stick with curtains.

Without curtains, criminals can scope out your house more easily.

Another example is, if you don’t care about privacy then why post letters in envelopes.

This argument falls over when considering that people do actually send holiday postcards not in an envelope. Why are people so relaxed about their holiday data?

When it comes to government privacy, a good argument can be that you might trust the current people in government, but does the system offer enough protections to protect against future regimes? If you're talking to someone who didnt like Trump, there are probably examples of actions he took that they would consider to be abuses (and people on the other side would probably think the same about some Democeat leaders).
