I totally hear you and you are not alone in wondering about this. Most of the gardeners who've started Food is Free Projects around the world have found the opposite to be true. Initially it can actually be hard for people to accept the free gifts of seeds, seedlings or veggies since people are wondering "what's the catch?"

When I first planted a front yard garden, I started meeting a lot more neighbors and many wanted to get involved or had tools/seeds/compost to share. If you start sharing your ideas of growing and sharing food with neighbors and friends, you never know who may be interested or help the idea sprout.
