Every one of these "individual actor catastrophes" has just assloads of barriers to it. Take the "swarm of exploding drones" or "slaughterbots" if you're a douchebag. We do not have the technology for a swarm of a dozen one-inch drones to avoid crashing into each other, let alone carry out the intensely complicated task of tracking down human beings. Also, drones that size have a flight time of about five minutes. Also you would need to manufacture and attach millions of shaped charges, which, unless you're a state actor, is likely to kill the person doing it considering the poor life expectancy of people trying to make only handfuls of IEDs. Let's take something that's entirely possible using current technology. A small group of motivated individuals could purchase thousands of toasters and turn them into bombs and mail them all to politicians or schools or _____ and set them to all explode at the same time. But that doesn't happen. A group could use agar and antibiotics to breed up a bunch of highly-resistant MRSA and use syringes to infect half the grocery section at dozens of stores on the same day and in doing so kill tens of thousands of people. But that won't happen either. Just because you can imagine something and not think of a reason it's impossible doesn't mean it's a realistic threat.
