Ideally delivery robots should be state owned and accountable to democratic processes. They are a valuable and useful innovation to solve logistic problems. A way to reshape how neighborhoods are build and planned and make them more energy efficient.
Gig economy. You're saying that the state(s) should be making all the money and that they should have control over when people can order goods by saying that they should be the owners of the drones.
Currently, the owners of the vehicles are the delivery drivers. Uber, GrubHub, Seamless, DoorDash, Lyft, UberEats and InstaCart, are all outlets for people who have downtime to make extra money and it's also a great starter job to get experience for a resume.
I think that drones taking jobs is going to push people to disrupt another market and sorry not sorry but fuck anyone who brings up the car thing when you and I know go damn well who ever is reading this uses rideshare services and delivery services. You also got people who don't drive and use rideshare services and people who use them to cut the cost of getting somewhere if you don't want to spend money on fuel from traffic in the inner cities.
