You're convoluting a quantitative argument with a qualitative one. The parent comment pointed out some hard facts about nutrient density and farming logistics, and how the current model for vertical farming won't solve world hunger, on a nutritional level.

You respond with a qualitative argument that you can grow a business and/or industry and maje better technologies if you have profit.

The issue isn't that the technology isn't good enough, it's that there isn't as many nutrients (as in soil) in a city or apartment to grow highly nutritional food. You'd have to truck in bags of soil to do this, which isn't nearly as efficient as leaving the soil where it is and growing it there.
