Economics is simply the study of the economy - something that is intrinsic to all human societies. At the simplest level it looks at the resources expended to produce a good and the value created by that good. If the good cannot recover the value of the resources consumed during its production then that good is not economic. That is why goods like organic farm produce that consume more resources than alternatives must cost more. Value judgements are irrelevant.
Listen, your insistence on pushing neo-classical liberal theories of economy as though this idea of a "self-regulating" economy isn't anything more than a myth has no sway with me. The "Market Society" that you're talking about was created through massive centralized bureaucratic organization and legislation throughout the 1800s. Agriculture is a part of that society that was created. However, my point, that either you refuse or are incapable of seeing, is that this entire social system (both politically and economically) is artificial and not the result of any "natural" processes. You want to talk about the value of resources as if there's something intrinsic about it and there isn't. I do not accept that perspective of economics.
More specifically, I do not believe that human activity and nature are commodities to be bought and sold on the market in the same way as manufactured goods. Human activity, that is labour, exists without markets, and so does nature. Land ownership is nothing more than the parceling up of nature. It exists without markets. Our use of the land, hunting, gathering, subsistence farming, would exist without markets. We rely on nature to survive. How we are socially organized ought to be predicated on the redistribution of resources to meet our basic needs; these are activities that predate market society by thousands of years. It is only since the 1800s that we've fallen into this destructive arrangement of the Market Society. Liberal economics was based on faulty assumptions about a particular period in time where society was transitioning from feudalism to pre-industrial capitalism. There is nothing natural about people
competing to sell their human activity to another. There is nothing natural about needing to sell your body to an employer in order to afford the things you need to survive. There is nothing natural about "buying" land. This was crafted by state intervention from the Enclosures, to the pauperism that resulted from the Victorian Era Poor Laws (which undermined the need for the ownership class to actually pay a living wage), and was finally completed by the eradication of those same poor laws which left masses of landless people competing with one another for mere subsistence. The market economy for labour was a state fabrication that began in England and spread across the globe.
So when you talk about the "labour" needed for organic foods and how that's the reason that the prices are what they are, I contest the entire system that was created to make
natural food a commodity to be sold at a premium. I contest the entire shift in agriculture that created the need for genetically modified foods and the chemicals used in production, without which there would be no "organic" distinction. I find it ludicrous that food, merely domesticated and grown naturally is actually a
premium product when that's all we should have available to us. Just the fact that food is described as "organic" (not to mention bottled water) is a sign of the damage that our entire political economic system has caused and continues to cause to our
humanity.
