As my wife is fond of saying "Your google search is not a substitute for my medical degree".
I really don't know where to go with your comment. You misrepresent everything I said and make claims that could only have come from a superficial google search and equally superficial reading.
Prime example, the second paper you link states, quoting:
"Most plants generally benefit from elevated atmospheric CO2 concentration through the “CO2 fertilization effect”, which boosts growth and yield [19, 23, 46, 52]. However, this positive CO2 fertilization effect strongly depends on the plant functional groups and species [7, 22, 53,54,55,56]. Even within the same species of winter wheat, the results from previous studies are inconsistent [22, 50, 57,58,59,60]. These contradictory results suggest that different plants and/or species may have different optimal CO2 concentrations for their growth.
Our results showed that the optimal CO2 concentrations occurred at 945, 915, and 1151 ppm for the aboveground biomass and at 915, 1178, and 1386 ppm for the total biomass of tall fescue, perennial ryegrass, and Kentucky bluegrass (Fig. 1), suggesting that a strong CO2 fertilization effect occurred at different optimal CO2 concentrations for these three perennial grasses."
They found optimal CO2 concentrations that are easily twice our current average atmospheric CO2 concentration. Your own link.
This is why massive indoor farms use CO2 injection.
> Vertical farms are not cost effective compared to many, many other options.
You clearly are not informed. Among other things, I have been developing technology for indoor farming, or more accurately, CEA (Controlled Environment Agriculture). I have many friends who own and run various kinds of CEA facilities. No, not everyone is growing weed. For example, one of my good friends runs one of the most successful indoor farm operations in Asia. We also have relationships in the Middle East, where certain geographies are absolutely hostile to growing food and indoor farming is the only path to food independence. During the pandemic countries like Singapore quickly discovered their dependence on the outside world for food was extreme, they quickly set national objectives to use technologies such as CEA to become far more independent.

Sorry, you don't know what you are talking about.
