"The key to understanding the systemic security flaw of proof-of-stake systems like Ethereum is to simply recognize that "stake" doesn't physically exist. "Stake" is purely an abstraction, a name that developers intentionally made up to obfuscate who has access to the special administrative permissions needed to approve or disapprove transactions (which is most likely centralized amongst the Ethereum foundation and large investment institutions)."
