"It is just that regulated (I prefer the name public but anyway) markets offer the possibility of legal defense by definition." - I think you may be forgetting an
entire area of the judicial branch: Civil Court. You can, in fact, sue a business for: representing their product incorrectly, providing service other than described, not sticking to the contract you signed, etc, etc.
We could just as easily simplify, streamline, and reform the civil tort system to allow people to file and address legitimate issues quickly through organic, judicial means. But instead, people, for god knows why, believe it is easier and more effective to have politicians appoint a bunch of crony farts to pass hundreds of thousands of pages of regulation that make the 95% case of good business operation harder, while most often failing to catch/fix the 5% of time things go wrong.
Le sigh, I digress.
