My normal response to "I have nothing to hide" is: "Cool, can I take a look at your browser search/reddit history?".

These "quips" have their place. Hopefully, they make people think and at least consider the importance of privacy.
The safest bet is to say as little as possible when it comes to the internet.
Yet there are millions of kids who cannot legally consent uploading to Tiktok et al. I'm so glad this didn't exist when I was 9 years old. I'm not sure how 2020 9 year olds re going to feel about it in 20 years time.
Case in point: I had an ex whose grandparents lived in a mansion on a ranch in the Ozarks, and were very well off (some kind of corporate lawyers). Their public image in the community was one of great wealth and benevolence; due to some bad financial moves, they'd lost everything a few years back and their kids, grandkids, and great grandkids had scrambled to buy the house out from them, a loving gesture, so they could maintain their image. I learned of this secret (which itself isn't really shameful, people make mistakes, even big ones!) after a year or so.
They were both of the "we have nothing to hide," but one day I asked whether they'd like their neighbors to know about their penury; they told me to shut up and mind my own business.
Nothing to hide? Everyone's got something to hide, but for the most part we don't know it, because they're hiding it!!
In this time and age, I find that highly doubtful.
********* see!
--------Now, tell those same people they'll have to pay a tax based on the destination they choose for holidays, and you'll get them in the streets (I'm exagerating a bit, but you get the picture)...
"I have nothing to hide" implies that everyone should be open to investigation.
I'm hiding it from:
- a future where the nazis or another totalitarian party wins the election
- future corrupt police personnel
- other countries intelligence (not everything I say might be compatible with doing work in North Korea/China/Israel/Saudi Arabia/Turkey (edit: added Turkey, I don't plan to go there in my holiday anyway)
- Leaks from police IT systems
And then I point to Turkey who went from approaching membership in EU to human rights hostile dictatorship in two years.
Or they actually don’t, because they do nothing of consequence on a computer.
It doesn't speak to Internet surveillance directly, but it's enough to show that there's more to privacy than the desire to conceal wrongdoing.
Edit Also, there's a great 2007 paper on this kind of thing, 'I've Got Nothing to Hide' and Other Misunderstandings of Privacy:

It's far better to ask why we should have encryption (for our safety, our security, and yes, our personal privacy) rather than whether we should have it. The government, with this bill, is debating whether we should have it, when it's obvious to the people that we definitely should. Turn that around on the senators proposing it; ask them if they want to build in back doors into our digital lives, can we as their employers and electors do the same thing to them?
E.g., maybe a govt comes into power that is strongly anti-gay, and punishes you for being pro-gay rights.
Or the opposite.
In general the idea that the government will always be reasonable and should have unlimited surveillance powers is unsound and unappealing.
Mind if I riffle through your contacts? Is it ok to DM any cute people I find?
"If I have nothing to hide, then you have no reason to look."
Nothing to hide is an incomplete sentence. Nothing to hide from who? Surly you want to hide your children from abusers and predators? Don't you want to hide your banking details from con artists and fraudsters? Your identity from identity thieves.. Your location from burglars, your car keys from car thieves or your blood type from some rich mobsters with kidney problems..
we don't know who are any of these things. So we should protect ourselves from all of them, in effect we have everything to hide from someone, and no idea who someone is.
