I would generally agree, but I see solving the problems caused by "cash crops" as very good and not unlike solar and wind solving the problems of extremes first.

If it can replace the 5% of food that is currently handled terribly and has an enormously oversized footprint then that is great.

I am not horrified by the ramifications of my staple rice coming from Asia on a slow boat which I then consume 100% of. I am horrified by all the tropical fruits that are being air-mailed and then largely discarded.

Once they are done experimenting, they will want to focus on what pays best and whether they mean to or not, they will be replacing terrible with better, while still not competing on very low cost/resource staple food.

I think there's no reason we can't eventually really beat plants on achieving higher density resource usage given seasons, light spectrum conversation, wind, etc, but it is a mistake to focus on how far off that is as a reason not to begin the process.
