It's comically complicated once you get into the details of moving an existing chain over from PoW; the Ethereum developers have really been working on it for years and only now have it in a shape that works for multiple Ethereum clients on a shared test network. If PoW weren't a climate disaster it would have very obvious appeal due to its orders of magnitude simpler implementation.

So why hasn't there been any new POS coins? If the complexity is in maintaining the history, new coins wouldn't have that problem. Even outside of any hypothetical technical complexity, a system that explicitly pushes all the power to those with the most money seems antithetical to the point.

  There are tons of them, looking at the top 20 coins here: https://coinmarketcap.com/ https://coinmarketcap.com/ - Solana - Cardano - XRP - Terra - Polkadot - Avalanche - Polygon That's the majority of actual chains in the top 20, since many of the rest are tokens running on top of other chains (USDT, USDC, SHIB, BUSD, &c) In general, starting a clone of proof-of-stake Ethereum is a very popular way to make a new chain. As for the philosophical point, PoW isn't really different. It takes tremendous capital investment to produce enough hash rate to ever mine a BTC. These are all more or less systems in which the rich get richer and the not-rich get to gamble.

What power do PoS stakers have? They select the order of transactions. That's it. The goal is to distribute this role across enough people so that they cannot collude to censor a transaction. That's essentially the only goal.
