You don’t use the garden to grow all the food you’re going to eat, you buy bulk goods like rice and beans, pasta, etc that you can get for low cost in bulk and then replace the greens and veggies a healthy person would get at the store with food from the ground which has a fixed labor cost instead of a ballooning dollar cost.

This. Lots of useful vegetables aren’t even bulk producible because of natural properties that make them hard to grow in large industrial scales. It’s the micro-nutrients and supplementary food content that a community garden produces, not your major staples. You’re not growing a corn field in metro Brooklyn, that’s not the point. But it doesn’t actually take much effort to add some locally grown lettuce to your diet from a community garden instead of shipping it all the way from California, and it reduces demand therefore lowering prices for everyone else to do so.
