Dairy, Cheese, and the Post

Saturday the Post's editorial board weighed in on Dairy Management and cheese.  A paragraph:

Constitutional is not the same as wise, however. Even if this national cheese-peddling corporation doesn't waste government money, it wastes government authority. Dairy farmers are perfectly capable of buying their own advertising. And shoppers are perfectly capable of deciding whether they want more cheese or not. The federal government's only role should be to disseminate objective nutritional information free from conflicts of interest, real or apparent. Working to increase the demand for certain commodities is the epitome of big, stupid government. We'll be very interested to see whether the new Republican House has the courage to say so.

I believe they're wrong because they're ignoring the "free-rider problem" here. The only way for farmers to coordinate and to be sure everyone pays their share of the bill for advertising is to have the government enforce the rules.
