The issue that arises from this approach, as I’ve found, is that people have something to hide from you, but not the government/large corporations. When they feel as if they are in a pool, they feel less important compared to being singled out by you.
You could instead do something similar: “Why does the FBI need to know what color of underwear you wear?” etc. to help them realize that surveillance goes much deeper than they realize, and not everything is relevant information.
I love fostering discussions, and I’m glad to see you do too!
Obviously nothing good can come if we all turn into the Borg. However, the question becomes more interesting when you consider different people. Should all of your information be known? No, obviously not. Should all of the CIA’s information (besides the personal information of others) be known?
My previous counter question assumes that no, not all information is of equal value. However, even if the value of information differs, your ability to control if that information is shared should not be diminished.
I had a boss that would remember everything you told to them, and would make incomplete assumptions about it. If you told them you liked dogs, they would assume dogs are your favorite animal. If you told them you got scratched by a cat, they would assume you absolutely hate cats. In this context, “mundane” information such as my personal preferences (favorite animal, etc.) is not something I would want to share with my boss, since nothing good comes from it. Even though the information has “less value,” the value of it was raised depending on who I told.
Your social security number is high value to say, your neighbor, but not necessarily the DMV. CIA documents may be high value against other countries, but it might be worth making it available to national citizens. So, information itself does not have a set value above any other piece of information, but it does have differing value depending on who you share it with.
