Is there not a middle ground of food delivery? Nonperishable foods can sit out for several days before use, significantly reducing the risk.

Likewise with wiping everything down when you get home. Supposedly soap is effective - it's not difficult to soak everything in soapy water. You can't completely eliminate all risk but you can certainly mitigate it.

Food delivery services are overwhelmed in many areas. It's better that those of us in good health continue doing our own shopping, and leave the available delivery slots for customers at higher risk.
