There are more variables involved, such as very short days with the sun low on the horizon, the ability to run 24/7, the heat loss costs, security, abundance of cheap clean hydro-electricity, and a hundred other variables. Sunlight is one of them, and we can eliminate that as a production - limiting input.

The Canadian government used to grow weed in an old underground mine.

Weed used to get grown underground so no one could see it and was under lock and key. Don’t need that for lettuce and tomato. And I do get that greenhouses can use supplementary lights, insulation and heating to extend a season or control flowering. Taking it into a fully sealed building feels like it’s crossed a tipping point. Seems to me at some point food preservation and transport of canned goods could still be a good alternative.

There is not a single solution for all use cases, like energy sources, there are many.
