Imagine someone taking control of your door and telling you you need to pay them $50 at a random bitcoin address before you can open it. $50 isn't a reasonable payoff for most carjackings, but this isn't like a carjacking. They're doing the same thing at the same time to 1000 people using a script they wrote. That changes the payoff, and that means more people are likely to try to do something like this. This is an extremely mild scenario. It's possible I'm wrong about IoT, and there's a case for using it in its current state. But one thing I'm _sure_ of is that analogies with cars don't work.
