Ad-hoc drones being able to take off, fly and land anywhere? Sure, at least in theory. In practice, even Amazon and various well-funded, profit-driven players couldn’t make it work (drone delivery was very hyped up ~5 years ago) so I have no expectation that an incompetent government will achieve anything other than getting fleeced by consultancies.

In addition, the Amazon/DoorDash model isn’t even what we’re talking about here - this is a predefined, specific route with the last mile still handled by conventional vehicles, so it is even worse.
