No tools can make Bitcoin private, unless it hardforks, it's a transparent public blockchain. You can get some some psuedonymity via coinjoins, but all your transactions are still 100% visible.
A good analogy for coinjoins is walking around naked, but you have a bag over your head...no one knows who you are, but you're still naked and vulnerable
Right now you have privacy options like cashu and for sure it will come more things. My point is if we have a strong money like bitcoin and still we can improve for privacy and other stuff why use another coin?
I know there are no anonymity but we have onchain pseudonymity and second layer where we can build more privacy and censorship-resistance tools.
Yes, Cashu has very strong privacy, but it is not Bitcoin. They are tokens that have no connection to Bitcoin. It can only be used with custodians and reintroduces seigniorage. Even the creator discourages people calling it a Bitcoin privacy L2
My point was you can never improve the privacy of *Bitcoin itself* without hardforks. Layers always come with different major trade-offs versus L1 privacy like sovereignty, security, complexity, and usability so will never be a full substitute for L1 privacy like Monero.
