Just because something is only a small portion of the final product, doesn't mean it's negligible overall. If say it raises the price of food by 10%, that's 200 billion dollars lost in just the US. Probably the price increase is smaller than that, but it would still be a non trivial amount of lost value.
And again, the real issue is with third world countries, where the price of food can mean life or death. These countries depend on the first world to innovate in things like GMOs. If we stop doing that, because people won't buy them, we hurt the world's poor disproportionately.
