That doesn't scale, and it's sometimes even illegal. We /used/ to deal with market failure and make sure basic services were met by creating crown corporations. Imagine that the Westons had to compete with a public company that got basic food goods from the farms to stores at industrial scale and at break-even costs. Heck, it could even lose money in remote areas where people can't currently access healthy food as the healthcare savings would be a great investment. It wouldn't have to be fancy, and it wouldn't have to include anything highly processed -just basic, healthy grocery goods that meet our needs. The capitalists would do fine, but would have to either actually be more efficient than the publicly owned system, or rely on premium goods for their profits (which they already mostly do anyway).
