Hell you don't even need to go that high tech. Just make model jet aircraft cheaper, easier to handle, maybe even autonomous and I'd like to see those current anti-drone countermeasures stop it from zooming in and dropping whatever dumb payload someone could possibly want.

Honestly I feel like a model jet aircraft is a lot higher tech than my proposal :P

But certainly lots of ways to make use of autonomy, and I'm no expert on the best way.
