People with food stamps but no money still need to buy things that cost money (e.g. new glasses, bike tire repair). The solution is to sell their food stamps for cash, and the black market only pays ~$.80 on the dollar. It's more efficient (and less patronizing) to give people $1000 to spend as needed than to give $1000 in vouchers, requiring them to jump through hoops to extract the needed cash at a 20% loss.
