For open blockchains, sure. Cash was the OG anonymous money. There's a reason that neither CipherTrace, Chainalysis, nor Integra FEC got the IRS bounty for successfully tracing Monero transactions with all privacy features enabled. The latter two got a $500k grant to try, with $125k available for successfully tracing, but neither claimed that final $125k. This also isn't an either/or where one crypto will win out. Different cryptos will continue to focus on different use cases. Bitcoin is one step removed from FIAT and just as traceable, but it's the first step you need to go from BTC to other cryptocurrencies - XMR for privacy, ETH for dApps and smart contracts, XRP to see what a CBDC will look like, LUNA for involuntarily donating your money to some south Korean guy, etc.
