Certainly for commodities at scale, no beating the agricultural infrastructure.
But for a premium produce for a premium product, it can pay. You may not even be able to get from a grocery store, what you can grow for your own needs.
Yes, but you can also grow that premium produce with traditional agriculture at a lower cost than these alternatives.
It's just that most big farms want the most cost-effective use of their land.
There's an argument that this process facilitates some market for people to pay a premium for produce grown inefficiently, but people also pay a premium for their local farmers markets to grow exotic stuff too. Traditional agriculture still wins, all things being equal.
Most restaurants don't have a farm. And land costs are quite high right now - out here in Iowa it averages $7500 per acre. Most of it not for sale anyway. Planting/harvesting machines can be half a million.
The flexibility of e-ag may yet have a place. Weather, season, rain don't have to matter.
Companies are already selling LED growing units for inside the home for food (like aero-garden). The interest is there, what's missing is for it to make significant inroads into the grocery/restaurant food chain.
There is simply no beating the energy output of the sun for agriculture purposes.
These systems are certainly worth study, but as a commercial operation it's basically snake oil.
