That isn't the point ser. The point is about the tradeoffs. That if someone who knows he has clean UTXOs simply wants "a little" privacy without the taint, Wasabi would be the better choice than choosing a mixer that will comingle his UTXOs with Mr. Heroine Dealer's UTXOs.
What are the tradeoffs? I don't understand. If they want to escape from the centralized exchange for a while, deposit coins on their Wasabi, mix them using the censoring coordinator to make a few transactions and return to the centralized exchange, then it's meaningless. Their money is analyzed by chain analysis companies, which are likely cooperating with every centralized exchange out there.
Again, an employer isn't going to look into the chain. They'll probably just give a call to Chainalysis, Elliptic etc., and they'll happily assist their new customer. But, if they don't use a centralized exchange neither do they pass the arbitrary output test of the coordinator, then they'll likely get the obfuscation they want.
In the end, if the coordinator or their analyzing company isn't cooperating with centralized exchanges, who tells you they won't consider those "taint"?
The problem begins from centralized exchanges.
