You're not getting the right context, and missed the actual point completely. If you're merely a casual user/newbie who simply wants to use a mixer without the risk of tainting your coins, where can you go? What can you use?
The correct answer is nowhere because every chain analysis company that I've seen has a section for CoinJoins and considers such transactions as "tainted" which means using Wasabi would also introduce "taint" into their coins even if all the participants had 100% clean coins.
What you need to remember is that "taint" is a fake concept created by chain analysis companies. At some point in the future they could even start claiming that "any coin they can not deanonymize is tainted".
