What "watch list"? Using ANY mixer definitely WILL put your PUBLIC ADDRESS in a watch list in a database somewhere. Using a centralized exchange could possibly do that too.
According to the document I quoted extensively above, so much as withdrawing your coins to your own wallet which has not been linked to your KYC data is enough to put you on a watchlist. It is quite clear the future the governments and authorities around the world want for bitcoin: Only to be used on centralized exchanges under extensively KYCed accounts. No decentralization, no peer to peer trades or exchanges, and no use as a currency. Buy it on a CEX, store it on a CEX, sell it on a CEX, and anything else is prohibited, which would obviously be the death of bitcoin as we know it. This is the future that franky1 is supporting.
About WasabiWallet, OP's concern is "taint". Wasabi's developers make sure that all UTXOs that enter their pool don't come from questionable sources. They merely want to protect their users from taint.
And who defines what are "questionable sources"? I discussed this before here:
https://bitcointalk.org/index.php?topic=5286821.msg60373127#msg60373127. The most hilarious example is this: Under Wasabi's terms, they will censor people from paying for hosting the bitcoin whitepaper, since in some stupid jurisdictions known scammer CSW owns the copyright.
