Part of this question, that I did not communicate very well, is that the problems that we face on a daily basis are because of the intense congestion with our airspace system. So, the one off Automated Russian Rocket does not cut the mustard in my estimation. Primarily, because there won't be 1 drone flying per day in restricted airspace away from populated areas. As we, and 1000's, of airplanes take off and land in Newark, JFK, La Guardia, and Teterboro, it only takes 1 mistake to have 2 drones raining down on densely populated areas below.

So, when I originally asked the question and said, not the theoretical, but the PRACTICAL, this was what I was referring to. My apologies for not painting the operating atmosphere properly, hence the tolerance for error much less.
