I believe the “grow your own” suggestion is intended to be supplemental, rather than a fully developed subsistence farm in your back yard.
The beauty of growing your own is that you can decide what you want to grow! There are some things which are very easy and cheap to grow (such as fresh herbs) that are actually quite expensive and inconvenient to buy! Other things, such as potatoes, are very cheap in any grocery store (when purchased in bulk) such that growing your own is more of a hobby/curiosity than a budget saver.
Tomatoes happen to be one thing you can grow at home that are simply far more delicious than anything you can get at a store. Sometimes you might be able to get nice heirloom tomatoes at a store but they tend to be very expensive and usually seasonal.
If you get some experience growing tomatoes then you can produce a pretty large crop in a relatively small yard. With home water bath canning you can then outfit yourself with up to a year’s supply of home made pasta sauce (or even simply peeled and blanched tomatoes with basil leaf in the jar).
