To me, this is the main argument for privacy. When I hear people say "I've got nothing to hide, so I've got nothing to fear", I immediately think "Well aren't you lucky?"
Having nothing to hide is a privilege, but the weird thing about that mentality is that I think very few people actually have that privilege. How many people, for example, would not be negatively impacted if the text conversations around their last relationship breakup were made public?
We all have vulnerabilities, and privacy is about choosing who we trust to know them. So anyone who believes that they have nothing to hide is either unaware of how dangerous the world is, or hasn't properly taken stock of what could be used against them, and how. Discrimination is one of the most common ways that your vulnerabilities can used against you, but it's not the only one.
I've thought about, and used, two possibly opposing, strategies to make life easier for others:
(a) Insist on privacy especially when you have "nothing to hide". I once refused to send a photo with an application (which is still a thing with the really slow-to-adapt companies in my country). I'm square in the majority in any characteristic a photo may reveal, but I was hoping to give some cover to those who don't want to give a photo for whatever reason, and fear being judged just for that.
(b): I'm rather careless with some information that others would be afraid to reveal, hoping to normalize it ever so slightly. There are still too many things that are really really common, but taboo to mention because nobody knows how common they are because it's taboo... Examples may be mental health issues, being bisexual/poly/etc.
Also, if you are in high regard and can afford it, you can do everyone a favour by rejecting certain common but harmful practices: Are you no longer productive at 4pm because you didn't sleep well? Go home!
It's interesting that your two strategies are apparently opposed to each other, but I guess the distinguishing feature is that you reveal things that might disadvantage you, and hide things that wouldn't.
