Please stop comparing The DAO hardfork to potentially executing a hard fork today. Ethereum back in 2016 was a niche blockchain in its infancy. Uniswap hadn't been invented, defi didnt exist back then, ERC20 tokens were still a year away from being created, nobody had heard of the term "nonfungible token", and major institutions treated crypto like it wouldn't exist in 2 years. Ethereum today is the home of 57B worth of assets because people trust in its security and decentralization. Hard forking at this point would compromise this very ideal and set a terrible precedent moving forward. On top of this, it's extremely unlikely you would get enough of consensus to agree to forking. Not only would have to convince Ethereum validators to fork, you would also need agreement from major parties like Circle and Tether to agree that the forked state is the valid state of the chain. Otherwise, issuance of assets and determining the "right" chain will become a huge issue. Finally, think about all the activity that's happened post hack. So many people have traded Ethereum and other assets based off of this hack. Hard forking now would have implications across all of crypto as well as tradfi. It's impossible to bring Ethereum into a state where we all pretend like nothing happened.
