We may just live in very different places. When I lived in Seattle farmers market prices were crazy. Living in a different part of the country and in a part of town closer to farmers, our prices are much better. We also use a local CSA, $20 per week for a decent amount of whatever is in season.
I also have a pretty large garden, we don't spend all that much time on it. We don't plant as intensively as most people think about. We don't till and keep the dirt bare, its more of a food forest at this point but we do still plant annual produce in rows in some areas. We spend maybe 3 hours per week total in the garden during the summer.
Raising livestock doesn't mean your life has to revolve around them, its all up to how you choose to raise them and what you raise.
> In all cases the economies of scale in industrial farming trumps local operations.
Have you ever been to an industrial farm, feed lot, chicken house, or slaughterhouse? If not I'd hold judgement on the value of that scale until you see how the animals are actually raised and treated. I'd extend that to crop fields as well, though its harder to empathize with what a plant when they're so different from us.
