We don't want base chain privacy. Those who do are thinking too short term.
Everyone will always be able to see what the big players do with their money as it's basically impossible to hide unusually large wallets moving massive numbers of coins. This keeps large holders susceptible to public scrutiny, the larger the wallet balance the more scrutiny. It's only not private for plebs right now due to KYC and tracking associated UTXOs. Once Bitcoin becomes generally accepted and exchanges aren't needed anymore, because most transactions occur P2P and non-KYC, then it'll be much more private for plebs who grow a reasonable amount of savings.
There is nothing wrong with the current semi-private nature of the Blockchain.
