A drone can do none of these things. Perhaps if I had a 'drop box' the drone could drop the package in, with a ramp top that slid the package into a weather-resistant interior (like a public post office letter drop box - anybody remember those?) it could work.
So I imagine drone delivery will be initially restricted to registered clients (commercial/industrial) with special installed receiver boxes. Not a small win - many package deliveries are to commercial customers!
