Although I hold some Bitcoin in ETFs, I think it would actually be a good thing for global individual sovereignty if Coinbase got hacked. A lot of the people who only care about NGU (suitcoiners, Blackrock, etc) would get rekt, while humble plebs would be vindicated in their HODL strategy.
Sure, there would be a significant temporary drop in fiat-denominated price, plus a new wave of anti-Bitcoin propaganda. But those who care most about the Bitcoin ethos would gain a significant win in the long-term war against predatory banking and authoritarians.
