Is the concept of someone who usually doesn't eat potatoes getting a bag and spending the next week making some potato dishes really that inconceivable? I don't doubt that this will lead to some waste - I've thrown out more half empty potato bags than I would like to admit - but that's a very negative outlook.

Also how do you choose between negative second order effects? Salting roads creates negative effects for groundwater and plants which are really hard to mitigate. On the other hand the second order effect of people slipping could at least be dealt with on an individual level by putting spikes on your shoes.

First off you have to identify them. Until you frame the costs and benefits of salting, it isn't clear that the real question is how can we improve pedestrian and vehicular traction without poisoning our plants and water supply. (I'd argue it's frequent ploughing, gravelling and dynamic signs for signalling when chains/snowies/AWD are required.)
