Lots of good points you’re making there.

I think the way it could be approached would be for a government agency to start doing their own, force company to report the information to their service, and to provide the service free for individuals, and cheap for corporations.

It would then be relatively fair for individuals to be allowed to deny these companies the right to get their data

This way, the credit agencies would be free to do whatever they want, but they would have to step their game up, or just get obsoleted.
