You said something interesting: "... modern life requires accidents like this."
This is a completely baseless claim. It is entirely possible to have both a technologically advanced civilization and simultaneously one that doesn't have catastrophic industrial mistakes like this.
How would we know such a society is possible? There's zero proof of that to date. Errors and inevitable catastrophes are part of the cost of a highly complex technically advanced society run by humans.
Not with humans.
Is it? Because at the very least, modern life involves the mass production of plastics, mining of various minerals, and the use of copious amounts of energy. That last one is only kind of solved (as long as everything works and nothing breaks), but I have yet to see any convincing evidence that there is any feasible substitute for the first two.
