I mean you're essentially describing DoorDash + competitors and HelloFresh + competitors. But in the restaurant industry proper it's the same thing except your exit isn't to get bought by McDonalds but to secretly dominate the mid-high tier dining scene in a given area and collect all the profits. So they won't build a bunch of the same restaurants but will take on massive debt to buy everything in a trendy area. I didn't really expect that in 2018ish that there would be a pivot from these companies to a real-estate play so they don't even have to own the restaurants anymore but can force them to use the company payment system and suppliers but it makes total sense in a boring dystopia way.
