A good example of your point that the free market is being twisted by specific commercial interests for the sake of "efficiency" is limited liability businesses. In general, the law imposes on those who enter into business the responsibility for any injuries they might cause. When a business incorporates, however, the owners are only liable to the extent that they have invested, not the extent that their business causes injury. The general excuse for this deviation from the common law is that it creates more efficiency and productivity because more people are willing to invest (knowing that their risk only extends to the amount of their investment). Such a system, however, raises real moral concerns. If the efficiency experts are to be believed, the owners are only willing to take part in the business because they are insulated from any liabilities that the business might incur. The obvious conclusion is that the investors believe the business is too risky otherwise. But if the business is too risky, shouldn't we wonder why we want to make it more financially attractive?
Knocking the limited liability corporation? Audacious.
