One of Ethereum's core goals is decentralisation.
How does Ethereum plan to deal Proof of Stake naturally monopolizing block creation and the Ether supply? In my estimation there are many compounding factors such as MEV and liquid staking with a massive economy of scale for first movers that combined with staking interest might make the top staking provider eventually hold the vast majority of Ether.
If the company that runs Lido is responsible for validating 99% of the blocks and the US Treasury Department comes knocking with a list of bad actors to blacklist, what happens next?
