What if we encapsulate social activity as it pertains to acquiring food? Let the grocery stores move their registers outside. Let their employees retrieve the items listed out per order. Use Task Rabbits or the equivalent to move food between the grocery stores and the homes.

Benefits include the ability to limit hoarding. We can also focus testing on task rabbits, to make sure they are healthy, and if they are not, then ask them who they've come into contact with?

Notice also that any jurisdiction which adopts this practice provides an opportunity for an observational study.

Apparently Wuhan has done something similar.
