That's, what, people evading regimes? Is there literally anyone else truly affected who isn't a bad actor?
Those curious, paranoid or with unique threat models. The same ones who distrust banks and use only cash. (They, like anyone using a mixer, should maintain records in case they fall under suspicion.)
Using a blockchain that's designed to work this way, and then claiming to need tools capable of laundering money in order to avoid that outcome, doesn't strike me as a particularly good argument in favor of either of those things.
