Won't Amazon and Uber Eats step in to fill that gap? I sadly worry that technology will fill in the holes. When reading the article I was thinking to myself: "what if people who lived there could pool their collective cooking skills and offer up meals to their neighbors (letting their neighbors skip cooking, a need previously filled by local restaurants)."
The people who live there are the ones who can afford to own a second home that sits vacant much of the year.
You really think people that well off are going to cook food to sell? -And- drive it (since who else is going to drive the Amazon or Uber Eats vehicles) until self-driving, on mountain roads, becomes a reality?
