Ethereum 2.0 will be protected by 1% of the supply. 1% of the money in the network will decide which transactions are valid or not. If angry miners go together and form a malicious staking pool with 1.5% of the network, they can block all the transactions or force the network to mutate. If a government agency does something similar, it's easy to create a killswitch of the network. This could happen if it is proven that North Korea, Iran or Russia use cryptocurrency to avoid sanctions.

Ethereum blockchain 1.0 is the safest bank in the world, and ethereum 2.0 is the opposite. Especially iun the few first months after the merge.
