A relatively small number of nuclear missiles is enough to wipe out human civilization. There's no such thing as "a weapon more powerful than even nuclear missiles" in terms of Earth-focused weaponry. And we've done very little if anything to prevent countries from acquiring and maintaining nuclear missiles. If we let North Korea have nukes, what makes you think we would try to stop countries from developing space capabilities?

Although dropping rocks at 50km/sec does save you having to build nuclear warheads, and you'd worry less about them getting shot down by missile defense. But global-scale strategic deterrents do get kind of academic past a certain point. There are plenty of ways for a nation-state actor to end the world if they really want to.

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.
