As someone who grows some herbs in pots, the people being discussed on this thread aren’t going to get vapors usin a jar of dried herbs that will last for a while. Admittedly you really need fresh basil for certain things but never had enough luck growing it to do more than stick a leaf or two on something for an accent. And gardening sure doesn’t cure a not enough time to cook problem.
I think there's two groups being discussed in this thread.
The ones walking out of the grocery store with $200 in groceries that fit in two bags. And families with low wages. The former is more likely to benefit from growing herbs and leafy vegetables as they are more likely to use them. Dried herbs can be pretty expensive as well.
But yeah, I only had one sentence about gardening in my original comment. Didn't mean to emphasize that as a groundbreaking differentiator in saving money on food.
