The problem is that a lot of these problems are only solvable within the network. Sure, if you steal a bunch of Ethereum, there could be a piece of code to reverse that theft under some conditions. But if you've cashed out, there's nothing the code will do. The code is only law within the tiny walled garden they've built. So not only do you have to improve the code, but you either need to prevent people leaving this walled garden so you can enforce your rules, or you create rules outside of the walled garden - which are called laws and the entire reason crypto exists was to evade those laws in the first place.

That's why these hacks are so often associated with Bridges - because the bridges are the locations where two different sets of rules are in force and you can exploit the difference between them.
