In your comment on Amazon, I think the difference is that often times, the white label goods are actually pretty good. So while it’s not branded, the reputation is overall positive, and sometimes these goods come from the exact same factories as the branded goods. While some ghost kitchens are derived from real, high quality restaurants, most of the time it is a distressed business that needs to rebrand or a new entrant of questionable quality.
I agree. Trader Joes has a lot of white label stuff, I'd say I usually have a higher impression of their white labeled products than branded products at the same price range.
Food delivery, even with all the complaints about how much they skim off the top, how much they underpay drivers, etc. still makes pretty meager margins. And consumers aren't blind to it; I know a lot of people who have grumbled about how much there is in fees.
I think there is room for both the physical and digital experience. Any restaurant who hopes to survive will need to make a choice about who they are, though - are you commodity or an experience? I doubt any can do both well.
The sad reality is that most people just don't give a shit - look at how much whitelabel junk is sold on Amazon to people who don't care. Those same people are the perfect demographic for commodity food delivery - they want some abstracted version of what they think Chinese food is for a reasonable price, delivered to their door.
The real scale of the problem will be when DoorDash et. al merge/acquire themselves a monopoly and push orders to their own entities.
