I think you're arguing too strongly from reductionist economic theories. I already am willing to pay significantly higher prices for brie over US cheese blocks, and I pay over the odds for tomatoes I like.
In Food economics, competition is not solely driven by price basically.
For example, why is organic farming not the predominant method?
The first comment on the articles page was addressing some of that impact.
Does it feed insects and birds and support biodiversity? Does it sequester carbon in the soil, making below-ground life healthy, increasing access of plants to nutrients, and hence produce healthier food? Does it help water infiltrate into the ground, this replenishing ground water and aquifers? Does convert sunlight into latent heat via plant transpiration, and thus support the Small Water Cycles that cool the surface of the earth and convey water (via rain) downwind to drier land? Does it engage the senses with beautiful sights and smells? Does it engage humans in an honest day's work, making them proud contributors to society?
To maximize the efficiency for indoor farming, you have to install these systems in the most arid or hostile locations where nothing has been grown before. For example, California or pacific north west doesn’t need this.
We can do better with crop rotation and crop diversity in most parts of the world where we grow food and it can be done in an environmentally friendly way.
