Hydroponics are limited to low-calorie foods such as lettuce, herbs, spinach etc due to constraints in the method itself. High calorie and/or high fiber foods require complex rhizospheres which is currently only found in healthy soil.
To add injury, the substrate used to provide nutrients to hydroponic plants either require petrochemicals or other plant material (compost, husks, seeds...) to mimic a complete nutrient profile.
Perhaps there are solvable problems, but given the already high costs and limitations, hydro is not an option if our ecosystems collapse.
