I like the big thinking! I agree that there are many tens of billions of dollars we could spend as we work our way down the marginal cost effectiveness curve of existential risk mitigation. Some other things to include are biosecurity interventions, preventing supervolcanic eruptions, comet detection and deflection (much more expensive than asteroid detection and deflection).
