There is nothing wrong with food delivery when used in moderation. I use DoorDash once a week to get a lunch delivered on a day where I have meetings running through lunchtime. It saves me time and hassle, and is a fun change of pace. It also came in very handy when a family member of mine was very ill and I wasn’t in the same city. I could order food and have it delivered to them. The service is nothing like cigarettes, where the only point of the product is to get you addicted enough to keep buying more, and eventually give you cancer.
That’s not to say that DoorDash et al. aren’t enabling people with food addiction problems, just to point out that there are very many real good uses for the service.
