How do you justify or defend the aggression being applied to the food producers? If they fail to comply, then they experience the aggression of the government.
Does the NAP only apply to consumers and not producers? Remember, everybody for the most part is both a consumer and a producer. Can you desire libertarianism when you are consuming and then bow to the state when you produce?
If we are to strive for an an-cap society, then certainly the most ticky tacky type laws applied to the market must be first on the chopping block. If insist on the government mandating something as insignificant as labeling, you are not ever get into the neighborhood of removing the military or suggesting private security is a valid option.
If you don't mind answering one of my earlier questions*, do you have any problem calling GMO labeling "Good government" or "good market regulation"?
(* I know I didn't go through your objections one by one. I will if you wish).
Peace and thanks!
