"All that needs to happen is all of human nature needs to change" No, just some legislation, policies, some new architecture, possibly some technology changes.

"All that needs to happen is all of human nature needs to change" No, just some legislation, policies, some new architecture, possibly some technology changes. If the government for example banned any org from collecting any personal information at all without specific explicit permission, and applied the same to sharing, it would quite fundamentally change the landscape. In fact, just taking a 'closed' approach to privacy instead of 'open' in most systems, then most privacy problems would be addressed. Obviously, a 'hacker' could steal stuff, but those are generally marginal cases, and there's no reason that we need to live with that either. How often to hackers steal money from your regular banks? Not very often. If we treated personal information like private data then we'd be living in a new world, about the 1990's.
