I think you're missing the point, though. Patients are much more likely to abuse/misuse an opiate, leading to much more than the "therapeutic" dose being taken. But most people aren't going to overdose on ibuprofen or acetaminophen. If they do, it's because they've made a foolish decision ("the pain didn't go away with one pill, so if I take five maybe it will"). When it comes to opiates, taking too much will generally be because of a chemical dependence, not a conscious choice. Even if the ibuprofen overdose is a stupid choice, it's still a conscious one.

> regular consumption of acetaminophen causes hepatotoxicity, too

That would be misuse/abuse, though. The bottle label tells you to seek a doctor's advice if you need to take it longer than a certain period of time. Sure, people can fail to read that and not know about it, or just choose that the risk of complications is acceptable given their pain situation, but that's still not as bad as chemical dependence driving the decision-making.

Don't get me wrong, I'm not saying we should ban opiates or never prescribe them, and I imagine the result of the backlash toward decades of over-prescribing has been a foolish swing to the other extreme. But I still don't think we should prefer opiates over ibuprofen/acetaminophen when the latter will do the job. Maybe that's not what you were arguing, but I do take issue with your suggestion that opiates are safer.
