You're suggesting that the act of eating out, or walking for takeout is going to stop for a sufficient percentage of the population that regular restaurants are going to disappear?
That people are going to pay a premium to have their food always delivered and that people actually want to be in their homes / offices all the time, rather than get out of their current place to go and do something?
Well as an extreme example: I can picture myself subsisting on Soylent every day, ordering from a ghost restaurant every other day, then visiting a restaurant for social fuel once a week.
I don't have a kitchen.
With the time saved I reckon people will find something else to do outside instead of eating.
