You won’t get anywhere if you use the “leave your bathroom door open” or “unlock your phone and give it to me” arguments, because to them that is a different thing and they pretty much know what it means to have privacy on those aspects. What they don’t care about are the things they don’t see (i.e. social media tracking, location data access, etc.) and that’s what they consider nothing-to-hide-nothing-to-fear.

So the best examples I could think of to counter those arguments are:

• Surveillance pricing
• Abysmal security of home security cameras

If they DO care that prices on the stuff they buy is influenced based on their habits and the data companies collect on them, or if they DO care that anyone can potentially tap into their home cameras to watch even just their outdoor cameras (let alone indoor ones), then they DO care about privacy and just don’t realize it.
