I ran into some similiar thoughts from a different product. One of the side benefits of Matt Colville's Strongholds and Followers for Druid's is that the natural nuts and berries inside their domain act like Goodberries.
Which really opens up some interesting thoughts, some of which can still apply to this, even though it seems we are fairly certain that wide-spread goodberry production isn't possible due to the spell only making 10 berries (which are still cheaper, though likely use similiar properties to the Bead of Nourishment in Xanathars).
Amongst my musings, I've figured that the biggest actual benefit to this is time. As you all have said, unless the caster is doing the work pro-bono a goodberry costs more on the open market than you would normally pay for your two or three meals a day. But, think about how long it takes to cook and eat food. Even with our modern conveinces and freeze dried foods, it is pretty difficult to cook and eat a lunch in 20 to 30 minutes. A "real meal" like dinner can take upwards to an hour. It would be reasonable to assume that if you were cooking and making food for a family in DnD, even at two meals a day, you might be spending two or three hours on food.
Goodberry takes six seconds to cast and six seconds to eat. And covers the same nutritional ground. If it is assumed that 6 hours of sleep, 2 hours of light activity to make it a "Long rest", and a few hours of the day is spent on food... you could potentially uptick the productivity of a populace by introducing Goodberries. Because people aren't spending time on those activities anymore.
I think it would only be 2 hours, and 2 hours for ten workers... might be worth the cost of getting a goodberry cast. Emotionally and socially though, I think it leads to a dark place if it is enforced by a company instead of chosen by a community. But, it makes for some fun Eberron scenarios I bet.
