Where are these drones going to land? That's a whole 'nother field of problems. Sure, driveways in suburban and rural areas, but what about in cities? Do we need helicopter pads on buildings for Amazon deliveries?

If there's one thing drone delivery is not, it's "simple". All of the work we did taming and mapping roadways and navigation has to be re-implemented for aerial flight. Every address needs to be mapped to a correct "spot" for a drone to offload it's package. Drones from competing companies need to figure out how to not collide with each other.
