I think this is also naive. You don't need an acre, nor is it backbreaking labour. The biggest time sink for home gardeners in my experience is watering, which you can solve by timed drip irrigation. Some plants like beans and peas are so easy to grow that they'll take over if you don't manage them. Potatoes are also pretty robust. However, growing year-round is hard. It's relatively easy to feed yourself over the summer/fall if you're dedicated, but maintaining enough to feed your family over the winter is much more difficult and requires planning (and if anything goes wrong you lose the crop). The biggest advantage for me is growing crops which are very expensive in stores and are easily wasted - like bagged salads, tomatoes that taste good, etc. Plus you can pick weird heritage varieties. We get a small veg box once a week and a small plot in our garden and we rarely buy vegetables when we go shopping.
