Author pointed out three problems with drones: 1. Battery life is insufficient. This one is true, batteries are not there yet. 2. Warehouses are far from target areas. This one is true as well, in order to make drones work warehouses/dispatch centers should be fairly close by. One solution would be to utilize hyperloop kind of system to quickly deliver drones to where they need to go. 3. Problem with delivering. This one is super simple. Make drone subscription costs high and deliver to customer a drop off pad. Make a clause in prime air agreement that you must find enough open space on private land for drop off pad to serve as drone beacon and unload zone. Drop off pad can have RFID/other location beacons that would let drone know exactly where it is. TL:DR author is right, while this can be built right now - it is simply not economical, and likely will not become economical in near future due to point #2 above.
