While I think it's a good effort, ultimately it would fail to have an impact. If archaeologists uncovered a similar message today, what would our modern reaction be? Probably a mix between curiousity and arrogance ("we can handle it")
We did uncover many such messages, only we had some problems deciphering the script. And so we forged ahead and for the most part we survived going into the places that were forbidden to us by the various gods of the past.
Yeah, but at some point, that's on them. As the authors put it,
>We consider the key to a successful system to be a credible conveyance of the dangers of disturbing the repository. We must inform potential intruders what lies below and the consequences of disturbing the waste. If they decide that the value of the metal component of the waste far outweighs the risks of recovering the metal, the decision is their responsibility, not ours.
