What do rights have to do with it? We’re talking about supply and demand. There is supply, there is demand, and the delivery apps provide the logistics to connect the two.
If we go back to the way things were 30 years ago then we have fewer restaurants, less economic activity, less diversity, and a less interesting life for everyone!
then we have fewer restaurants
No, we don't. People still have to eat. If anything, we have fewer restaurants today because of consolidation in the industry and the way massive-scale delivery enables ghost kitchens that take customers away from actual restaurants.
less economic activity
Uber Eats barely generates any "economic activity." It doesn't rate against the economic activity generated when people go outside.
less diversity
Now you're just making things up. People don't become Ethiopian because they sat on their couch to eat at Ethiopian delivery compared with actually going to an Ethiopian restaurant.
a less interesting life for everyone!
Leaving your house is more interesting than being inside. It's pretty much the definition of "living."
