Privacy is not the same as anonymity, people should not get this confused, you can use Bitcoin and have your privacy. Wasabi wallet that CoinJoins and Mixers can help in achieving high level of privacy, but did you still know you can use electrum to achieve high level of privacy? Just make use of coin control, coin freeze, address freeze and many other features in a way you can have high level of privacy, and if you are not yet satisfied, you can make use of mixers. Bitcoin can be used in a way all my transactions can although be tracked on blockchain but can not be linked to me.
You cannot achieve absolutely privacy with coin control. Doing so allows you to separate the UTXOs and avoid linking addresses together but it does not in anyway helps the user preserve their privacy. Transactions can still be linked, change addresses lowers the degree of confidence in terms of its association but in no way will it improve on privacy. CoinJoin and mixers are your best bet at it but there is always a chance of them compromising your privacy, either intentionally or unintentionally as well. Electrum is notorious for having mediocre privacy features and should not be used if you really care about it.
