That is merely a matter of attitude. Right now post-processed sewerage isn't used for food production in most First World countries, but it could be. It is often used on golf courses, and there have been experiments in bagging it and selling it to landscape gardeners as a replacement for bagged cow manure. In the DC area, there was Com-Pro in the 1990s, for example, though I heard it was taken off the market for lack of sales even though it was less than half the price of bagged cow manure. If there was serious need for fertilizer, it could easily be satisfied.
