You might be happy to hear that this absolutely exists in the wild.
The tiny garden co-op (only 2 folx mainlining), where I get a bunch of veggies every week, offers the choice of paying X per year as a consumer, or enjoy a discount if you agree to help ~15 hours a year with the weekly harvest. The socializing with good people you can get for free, if you're not that hermitically inclined.
If one is strapped for cash, that's a solid way to participate and get glorious food, on par with throwing money at the problem if you're stuck in old economy and cannot spare the time instead.
This co-op alone helps feeding ~50 people, with a surprisingly tiny sliver of land, for a couple years now.
Repair Cafés seems to be becoming trendy, too!
There's so much more potential for a new economy to literally sprout from the ashes of corporate slash and burn, but those ideas need more nourishment. People say "it'll never work!" until you show 'em it does.
