Good idea -- DoorDash has you covered!
They've got a variety of offerings such as "The Essential" and "DashMart", stores they own where Dashers can pick up food and other products.
Arguably, these services are all going to converge on virtuality soon, because it matters not to the consumer whether these places have storefronts, open to the public, or even a brand, so the "ghost kitchen" model here is inevitable.
Even chains which still implement in-house picking and delivery (Safeway, Kroger and others) will find it efficient to run locations totally closed to public traffic, no checkers or baggers or huge parking lots or deli tables necessary.
