Well for one thing, people would have some incentive to put the crop in very late if new-crop beans were $12.73, instead of below the $9.73 insurance price.  I'd love to know what you call "southern Iowa" you live in that hasn't experienced miserable spring weather in recent history, but maybe you farm 300 acres with a 16 row and have the luxury of doing it in two days then watching the neighbors.  I've spent and seen others spend thousands upon thousands of dollars side dressing, flying on urea, spraying Headline, spotting in drowned out areas only to get a 3" rain again the next night- all to maybe improve 85 bpa corn to 90 bpa corn and save the insurance co. a few bucks on the claim.  I'm fine with ditching the crop insurance policies, but not many landowners are going to be fine with the readjustment of land values to reflect the true risk of Mother Nature.
