Because the stakeholders become the new central bank, with all the same motivations and conflicts of interest. You end up with a “staked class” and an “unstaked class”.
This is a contributing factor to why ethereum can be rolled back: because the stakeholders didn’t like it.
Bitcoin essentially has the same thing though — it’s just that the “staked class” is those who have built power-devouring ASIC facilities to compute lots of hashes. Get enough of them together, and you can roll back transactions via a Sybil attack, just as you can with organized action by stakeholders in a proof-of-stake cryptocurrency.
