Perhaps, but as regulators step up it’s going to devalue things once people know coins from tainted chains are going to be harder to resell. That’s going to further increase the risk of using mixers since the people using them for ideological reasons are going to scale back their usage as it starts costing them money & adding risk.
P2P dexs dont care about mixer usage, you can always find a way to cashout if you have the private keys.
