> Of course, Domino's and lots of other places do it

They kind of go into this in the article -- that since Domino's has made delivery work for decades now, it must be possible to do it sustainably; and that although most of the author's restaurant friends considered it "not worth the effort", individuals had managed to make the economics work for their very specific circumstances.

BUT -- that the fact that it can be made to work in specific circumstances sort of undermines the whole idea of DoorDash, which is a generic "food delivery wrapper" around any restaurant. DoorDash by definition can't do the kind of integration that Domino's does.
