I think other models are much more likely. In Brooklyn, the pizza joint Roberta’s opened up a delivery only kitchen after building a successful restaurant. Others in nyc have opened restaurants after a successful ghost kitchen. In the food truck craze, often the successful trucks leveraged their brands to open physical restaurants.
I think industrial kitchens initially allow restaurants that already have a brand to send chefs to the industrial kitchen to handle the delivery load, saving the cost of restaurant space and making delivery logistics easier. I think industrial kitchens will also make it easier for a young chef to start building a brand with less capital.
I don’t ever see the model working where you go to apartment 301 to grab your takeout order.
The question is irrelevant. "Uber but for food" isn't going to be randos making meals on demand in their home kitchens, it's going to be increasingly massive (but regulated) commercial kitchens providing meals much like restaurant does. Food preparation benefits from economies of scale.
We can see egregious examples of displacing any form of accountability in the gig economy to the point that they are already immediately met with distrust and disdain when they encroach on another market.
