> What food delivery needs is someone to open big neighborhood commercial kitchens and pump out delicious, healthy, locally sourced food that is reasonably priced and maybe vertically integrated w/ delivery to eat some of the margin currently taken by uber/doordash/drivers.

Maple tried this in New York City. They had delicious, healthy, locally sourced food and more or less replaced my lunch orders while at work (they were not available in my outer borough).

They couldn't hack it, though - the margins weren't high enough and they ended up selling to some UK company and dismantling their New York operation.
