What do you mean "think"? We have two real-world data points right here showing cases where government regulation forced manufacturers to improve the quality of their products, and where if left to their own devices their own conflicts of interest would have gotten in the way of doing so. Namely, the inefficiency of dishwashers being a fully externalized cost, and planned obsolescence of light-bulbs ensuring that customers come back. Do you have any concrete arguments for why these two cases of successful government intervention do not hold up? Do you have any argument to suggest that the situations they describe are exceptional instead of common and all over the marketplace?
