I will admit, there are roles for government regulation in the marketplace. I simply do not know enough about the chicken I buy at the grocery to make an informed choice. I appreciate the health inspectors, organic labels, and other regulations that facilitate a free, fair, and efficient marketplace in which I do not need to know the farmer to be confident my chicken will not poison me.
However, I do not think lack of open (and understandable) information is the issue in this particular case.
Regarding your last point, I agree with you. The more interesting aspect here is not the implementation details, but rather the questions you're raising of free enterprise, the freedom to work, and the freedom to engage in free & fair commerce of your choosing.
