Why would you trust an unknown group of people to take all the proper precautions? Who picked the item by hand? Who is this bringing it to your door? Are you sure they washed hands? Did they accidentally sneeze on anything? Is the vehicle sanitary? Also, I would imagine people doing these jobs are probably at higher risk of being exposed, just by nature of traveling & being in public all the time.
I would rather trust my own skills to be responsible and protect myself, rather than other unknown entities to touch all my stuff. All the supermarkets I’ve been to have someone at the door sanitizing carts as the hand them too you. I am hyper aware of avoiding touch anything unnecessary. I can keep as much distance from people as I want. I know my hands are clean when I start, and then avoid touching my face until I sanitize after.
