That is fundamentally spending. He is spending his time to get your value. In practice we can basically ignore this from "economy" calculations though. While it happens, it's such a tiny part of the economy as to be irrelevant. Equally growing carrots in itself requires spending. Certainly your time, but also input costs with fuel, fertiliser, water and so on. Of course it is possible to live "off grid" and be totally, or mostly, self sufficient. Effectively to live "outside the economy". Again, while this happens, it's vanishingly rare (and those folks don't care about inflation)
