And my personal opinion is... even if mixers were used in a significant percentage for illegal activity, banning them means taking away my right to privacy. This is what people don't get: we're literally setting our own right to privacy on fire by wrongfully placing privacy and crimes in the same pot.
Agreed. Let's say we did ban mixers. What do people think is going to happen? Criminals will just throw their hands up and say "Oh well, that's my life of crime over, better go get a 9-5 job and be a law abiding citizen."? Of course not. They will use coinjoin, or payjoin, or whirlpool, or atomic swaps, or DEXs, or the thousands of ways they can launder cash which have been going on for hundreds of years. As the old saying (kind of) goes, if you make privacy illegal, then only criminals will have privacy.
That is because one of the main characteristic of Bitcoin is provide you with complete anonymity and privacy with your Bitcoins.
Bitcoin is absolutely not completely anonymous. If it were, we wouldn't need things like mixers in the first place.
