Do you honestly think that the number of drones will ever be more than negligible compared to the birds that we fly amongst every day?
Seagulls love to fly around the disk of a hovering helicopter. At least the pilot of the drone knows it will die and he will be out of pocket if he gets too close. Birds, not so much...
Birds are constantly doing the things which you are worried about.
They fly over airports.
They come to look at helicopters.
Airliners are specifically designed to take bird strikes.
Baby quadcopters seem very similar to me.

Do you honestly believe that normal human ATC will have any role when it comes to Amazon etc delivering parcels?
Why would a quad ever fly above 200ft?
Why should Amazon give a sh1t if ATC are stretched? ATCs job is to provide a service to everyone who needs it, not decide who has a valid reason.
Amazon has a far more valid reason, (ie business) than some PPL playing for personal entertainment.
