Doesn't it also require a ton of energy to move a five ton truck to my driveway in order to deliver a 100g charging cable?
I'm not sure the laws of physics are on the side of the status quo here.

Even if a drone could carry the energy equivalent of a 20 gallon fuel tank with it, it would waste the majority of that energy both keeping itself and its energy aloft.
Tires and other ground plane vehicles, mitigate the majority of that waste in exchange for increased navigational difficulty (regarding obstacles like buildings and trees but also moving objects like vehicles in its path).
The self-driving robots made some sense but only for very local (couple of block radius) delivery.
A paraglider drone with a tiny parachute would be more efficient than any 3/4/6/8 motor drone copter
the rest of the money went into the gas tank of the truck
you and everyone else who ordered a cable that day on that route chipped in to fill the truck up
