I think that should be obvious to everyone. Money Laundering involves doing something with money from illegal activities. Mixing is a tool and has nothing to do with illegal activities. It's a tool that can be used by anyone, including money launderers, but has nothing to do with money laundering itself. Just like if you own a knife that doesn't mean you committed murder, though you could use it for murder.
It's just like the Internet. People can use it for both good and bad things. There's nothing governments can do about it, other than enforce the rule of law whenever possible. Instead of hunting down crypto mixers, governments should hunt down people using these services for illegal activities. Not doing so tells us there are other intentions. We all know governments want to destroy crypto (or at least minimize its impact on the mainstream economy) because of its decentralized design. Especially anything that has to do with privacy. When they can't track or control financial activities, that's when you become a threat to the corrupt system empowered by banks.
I believe the future of crypto mixers lies in decentralization. The more non-custodial (decentralized) mixers there are, the harder it will be for governments to stop people from obtaining true privacy. I'm yet to see how it's possible to stop criminals from using decentralized mixers for breaking the law (money laundering, tax evasion, etc). KYC/AML is not the answer to this. We can't predict the future, so lets hope for the best. Just my opinion

ok here is a game for you.. you know what mixers do for innocent people.. now pretend the word MIXER was never invented. invent another work that doesnt meet the details of regulations but produces same end result for the user..
each time you keep saying "mixers" have to continue. is continuing the issue..
uber replaced taxi cabs.. so think outside of the box of promoting MIXERS
