...pain is far stronger than necessary as a warning sign.
It seems pretty clear to me that this was not true in our ancestral environment. It may be the case in our present artificially benign environment however.
That is precisely what I mean; but also note that there are circumstances in the ancestral environment in which pain is entirely useless, such as when one has been mortally wounded. So even in the worst case we can do better than pain, and in the current case I suspect we can do much, much better.
