The only thing I'd say is that historically the barley that isn't used for malt goes back into the feed industry. It makes it an almost fail-safe crop for farmers.
However, by opening up more markets we can encourage farmers to grow more barley because they'll get a better price for it. That sense of profitability is what drives it. Barley, as a crop, is very good for the ground, for soil, for sustainability for crop rotation. So it's good to get it back in the rotation, but it has to be competitive to be there.
