Except where actual safety is concerned, all information should be public. That means Individuals, businesses, authorities, governments, etc, should not be able to hold any information privately, it should all be freely available to everyone. There only private information is what you can hold in your head.
Anyone who thinks about this idea for more than 30 seconds decides it is a really bad idea. I honestly believe that true information freedom will also free the human race, and that is the unpopular part. Everyone seemed to think I'm naive but people are just frightened kids and secrets are their first line of defense.
