It's going to be interesting (and important) to compare this to a world where instead of being a smart contract Arbitrum was a company that could go bankrupt

Wasn't anything crazy. Just bad process. They should have a system for automatically topping up the sequencer. 

My Rollup Economics dashboard shows that they make more than enough profit to keep the sequencer going
