There is always a continuum of risk. By your argument, anyone who traveled to go view a historic monument is "just stupid", since there is a non-zero risk that they will die in a car accident along the way. If entering a burning building (which isn't actually _that_ risky) to salvage one-of-a-kind historic artifacts isn't something you would chose to do, that's fine. Don't label the actions of those that make a different choice "stupid".
