So do I (well, from my father's bees, that is...). But it illustrates exactly what the OP is talking about - this honey comes at low cost or free to us, but for the receiver it represents a much higher value. (prices around here for local, pure honey are 7 or 8 euros per 450 grams / about a pound). My kids sell my parents' honey for 5 euros and people are grateful for those low prices even, and treat it like we're doing them a favor.
I gift people some sourdough bread I make. The price of a loaf of bread is ridiculously cheap, much cheaper than my time would cost if I factored it in and my breads aren't perfectly baked every single time like a bakery with professionals can do.
Still, people appreciate it a lot, much more than if I purchased a better-looking loaf of bread from a professional baker for 2-3€.
I don't think it's necessarily tied to the value it represents to the receiver, it's the act of kindness with the unexpectedness of a gift that gives it value.
I used to do this but reciprocality meant that everyone started giving me back baked goods in return, usually really sweet stuff that I don't want in my diet.
I enjoy baking sourdough loaves to return favors though e.g. if s neighbour takes care of my lawn while I'm away. That's fun and keeps the books balanced.
