I don't think anthropic arguments can be used here because you could equally argue that it's more likely we're living in a universe where the laws of physics are such that high energy particle collisions are rarely or never world-destroying than it is that we're living in a universe where they are world-destroying, and we've just gotten lucky a whole bunch of times so far.

Also, we can observe that nothing world-destroying seems to happen on other planets that are also exposed to high-energy particles.
