This is in some ways similar to what happened to the radio spectrum. Large swaths are only licensed to commercial enterprises to broadcast trash while amateurs got squeezed into narrow slices here and there. No. Reserve 200-300 ft along well-defined corridors for commercial delivery services and leave the rest for amateurs.
The stuff I want from Amazon isn't going to be in stock within a 500 mile radius anyhow. I don't need tacos delivered by air.
