Because these government-favored CoinJoins are a threat to Bitcoin's fungibility, and therefore might make UTXOs that went through them "more valuable", what the user could do before using Wasabi's coordinator is like what Peter Todd said in the video. Use layers.

If you have "low value", "tainted" UTXOs from the Dark Markets, you could use JoinMarket, and use those UTXOs in Lightning, then send them to yourself. Convert them to onchain Bitcoin then use Wasabi CoinJoin. You now have "government-friendly" UTXOs read for cold storage. Thanks Wasabi!
