Yeah, privacy is a joke on blockchains. Perhaps that is why actually private coins like Monero are having such 'difficulty' getting adoption on mainstream platforms, with shitcoins getting preference. I suspect that if coinbase tried to add Monero, they would get a very angry letter from the CIA/FBI (perhaps this already happened, they have been having 'technical difficulties' adding it for years now).
