The UK has the Data Protection Act which does some of this.
One radical option would be to grant people copyright over their own PII (with about a billion caveats to allow journalism etc.)
Then you'd just see setups like the financial industry has. You get analysts, call them journalists, and have people subscribe to your publication. The journalists go get insider-ish tips and 'publish' them to a select group of followers.
With laws like that you'd just hire a full time business analytics journalist to cover your store.
