2 Million deaths are more than the US deaths of the Civil War plus WWI WWII, plus Viet Nam . Don't forget Spanish 'flu killed 18-20 million (recorded). in 3 waves. I would bet that US + Europe + Australsia (say) would be about 400 million then. Throw in India (& Pakistan) and you get to the 2-3% death rate.

As for conscripting/volunteering van drivers - surely the drivers would do the picking at local supermarkets. Clever ones would know when the lorries arrive and be able to be there when the shelves are stocked. The real problem is bona fides, vetting the volunteers/conscripts when the service is needed yesterday!

PS I walked 5 miles to town (along the pretty canal) and the rain forced a bus trip back. Life in the COVID-19 era is complicated innit?
