In 2022 that's a decent argument. I'm thinking a few decades in the future, when there is probably settlements on the Moon and Mars, and an asteroid mining industry that finds valuable metal asteroids and sends them to Earth orbit, maybe by attaching solar powered rockets to them. In that world, any asteroid mining operation can destroy a lot on Earth, even by accident.
