ELI5 WHY WE CAN'T "ROLLBACK" ETHEREUM?

Summary from the TLDR Crypto newsletter

Following ByBit's recent $1.4B hack, there have been calls for a rollback of the Ethereum blockchain to get the coins out of the hands of the North Korean hackers. This is technically impossible since the hack involved properly signed transactions rather than protocol-level issues, and the funds were immediately movable, unlike the 2016 TheDAO hack's month-long withdrawal delay. Ethereum's current interconnected nature with DeFi protocols, bridges, and real-world assets means any rollback would incur ripple effects across the entire ecosystem.
