Yeah that was my take as well. I think there's some sort of trade-off point here, though I don't know where it is. Yes modern outdoor agriculture is hyper efficient, although I think the author's comments about cash flow self-sufficiency gloss over a lot of government subsidies and bank bridge loans. In any case, indoor ag should be able to exploit the lower weather/pest risks, lack of need for damaging pesticides, consistent conditions, 365 day growing season, proximity to markets, etc. at least for some combination of products.
