Information is power. Information is used against you pervasively for control. This control ranges in nefariousness. You want examples? Here are some examples of consequences of use of information as a means of power:

• A present or future employer making HR descisions based on your behaviour outside of work.
• An insurance provider discriminating you and your coverage based on some knowledge like a pre existing condition or behaviour
• Behaviour that is socially acceptable today or appropriate in context being broadcast in the future when it is not or out of context
• Defamation
• Extortion
• Being targeted for having certain political thought
• Being targeted by perpetrators of acts of violence, theft, or nuisance (think swatting)
• Being manipulated into making purchasing or life descisions that are not in your best interest
• Systematic or discrete racial, sexual, religious or other identity discrimination
• ...

The usual response to a list like this goes something along the lines of, bah, none of that will happen to me, I'm a goody-two-shoes. That advice is about as good as saying "I'm a good driver, I won't get into a crash, so I don't need to wear a seatbelt". Back to my point, the consequences of information used against you are too far and too abstract for people to accept.
