(I made separate comment making the same point. Just saw that you already wrote this, so moving the couple of references I had here to unify the discussion.)
If wars, revolutions, and expropriation events continue to happen at historically typical intervals, but on digital rather than biological timescales, then a normal human lifespan would require surviving an implausibly large number of upheavals; human security therefore requires the establishment of ultra-stable peace and socioeconomic protections.
There's also a similar point made in the age of em, chapter 27:
This protection of human assets, however, may only last for as long as the em civilization remains stable. After all, the typical em may experience a subjective millennium in the time that ordinary humans experience 1 objective year, and it seems hard to offer much assurance that an em civilization will remain stable over 10s of 1000s of subjective em years.
