It seems to me that you are making a map-territory confusion here. Existential risks are in the territory.
If I understand the reasoning correctly, it is that we only know the map. We do not know the territory. The territory could be many different kinds, as long as they are consistent with the map. Adding SRS to the map rules out some of the unsafer territories, i.e. reduces our existential risk. It is a Baysian type argument.
