Many people surviving on EBT can't afford vehicles/insurance/gas - stuff EBT doesn't cover. It's unclear to me how they'll afford the costs of delivery since EBT won't cover that either, but more options can't hurt.
I'd much rather have people who are struggling get delivery if they can manage it than have them go into the grocery store when they know they're infected, or when they've got a vulnerable person they'd risk bringing disease home to.
