People spend money on privacy. This gives it value.

I don’t know anyone that would want to spend money on a hotel if there was a security camera in the room. I would get the more expensive room without the camera, probably go to a different hotel.

Doctor and patient confidentiality is implicitly understood. Do you think doctors should be able to tell advertisers what their patients are going through.

Maybe your own individual privacy doesn’t have value to you, and that’s okay, but other people value their privacy, and these corps profiting off data definitely find value in lack of privacy.
