I read the book, and I didn’t see much info addressing the criticism of growing hydroponic food. Also, I think that they need to show the math involved with how much energy they will be required to produce food, water, etc. The book just provides a list of the possible technologies.
Many countries and polities don’t produce enough food, i.e. Singapore, NYC, etc. That is what trade is for. There is no particular reason a city state can’t thrive without a native agriculture industry.
