Ryan, I accept your terms, though clearly if I am suffering from a cognitive bias I will be unable to detect it except through argumentation.
I will say that I tend to overstate the case for open source in the interest of shifting the public discourse, which seems to be almost completely devoid of discussion from both a public policy and practical ethics perspective. It is either seen as a hobby or a business model, but never as an ethical or political stance.
Sorry for sidetracking the discussion a bit.
I do think this relates to environmental concerns as well though, because genetically modified crops have a variety of environmental impacts. One of the environmental factors is actually the increased efficiency of genetically modified crops (patented or otherwise)
One thing that seems to fly over the heads of nearly everyone is the
efficiency paradox. As something becomes more efficient, people tend to do more of it. Even if you can engineer crops which use less water, less pesticides, etc, if industrialized agriculture is still fundamentally unsustainable then the problem only becomes worse. As its efficiency increases it will tend displace other forms of production, and the problem of unsustainability will actually be exacerbated.
There is nothing so useless as doing efficiently that which should not be done at all.
We should be leery of more efficient industrialized agriculture. It is by this same logic that we should be leery of higher fuel efficiency standards for internal combustion engines. The same is true for healthcare, and anything else.
It isn't how efficient we are, but what we are accomplishing, and who it is benefiting. Open production processes, since they are not based on profit, can take externalities into account, and can pursue goals other than profit. Open source projects solve real human needs, just as civil society projects of all sorts voluntarily cooperate to accomplish goals which are determined by the volunteers themselves.
Now, this isn't always possible in every case, and there are sometimes immediate utilitarian concerns which can override the concerns over process, but this doesnt seem to be the case for agriculture.
With medicine, I can definitely see a need for capital intensive industry for producing MRI machines, and such, even though preliminary open source MRI projects have been attempted. Yet, there is still enormous amounts of potential for open source with regard to drug synthesis, genetic engineering, pacemakers, cochlear implants, you name it.
Based on this idea, I think buying organic produce has two benefits. Increased sustainability and no proprietary GMOs. It likely isn't worth paying huge premiums if the money saved by not buying it can be diverted to good causes, but it is certainly worth a modest premium.
On the other hand, you could go one step further, toward
Open Source Ecology. Perhaps this is not currently viable for most people, but I have a feeling it will reach a tipping point in the not too distant future. They have shown the potential to drastically reduce costs by utilizing open source tractors, open source brick machines, self-produced biofuel, solar energy, and numerous other decentralized technologies. Perhaps this is the mode of production by which farming will occur in the years ahead.
