You like decentralized money without laws and accountability, but would like to have a central thing (TBD) that is accountable and respect laws? How would that work?
1. Upgrade protocol to include protections for well known cold wallets held by exchanges (ex: API call has to be made to the exchange's security endpoint to validate each transaction out of the wallet. Exchange staff would need to manually allowlist large transactions before they are transmitted).
2. Decentralized voting on reversal of transactions (90-95%+ vote needed to reverse to avoid 51% attacks)
People who control or take advantage of cryptocurrency don't want this to happen.
Couldn't you technically just 'git checkout' a previous commit from before the fraudulent transaction occurred and pretend it never happened? Isn't the real problem that you'd have to convince a majority of users to do the same?
Something like that would probably be overkill for individuals, but most people would definitely benefit from some added on chain bureaucracy regarding how their accounts are managed. And yes, for many this would lead to a system that isn't notably less centralized than the traditional banking system. But people would at least have a choice as to where their wallets gets to sit on the bureaucracy <> complete freedom spectrum. And even if they end up closer to the bureaucracy end, they'd have a lot more flexibility and lower administrative fees than what they currently have.
