Anyhow, I think we are wasting our time, those guys are never going to visit this thread again and engage in a real discussion.
They're not, but it's still worth correcting their nonsense for anyone else who will read this thread and may erroneously believe that only criminals deserve privacy.
Chainalysis, who are probably the biggest blockchain analysis company and who have over 200 customers including Binance, Bitstamp, and Bitpay, found that only 8% of funds passed through mixers are from illicit sources, with the majority of funds coming directly from exchanges, meaning the most common use of mixers is individual users seeking privacy from the prying eyes of centralized exchanges. You can see their webinar on the topic here:

I really think we should start by closing down exchanges that are not requiring KYC for deposits and withdraws under a certain amount.
What about people like me who trade exclusively peer to peer and never touch an exchange? Better just shutdown bitcoin altogether to be safe.

These kind of services might perhaps not be needed anymore because we people earning from legitimate source should never worry about the origin and destination of our funds.
Nothing to fear, nothing to hide, is an utterly nonsense argument:
I don't need to spend a lot of time dismantling the "nothing to hide" argument,
because it is already widely discredited. I will share one of my favorite quotes on the topic though:
The old cliché is often mocked though basically true: theres no reason to worry about surveillance if you have nothing to hide. That mindset creates the incentive to be as compliant and inconspicuous as possible: those who think that way decide its in their best interests to provide authorities with as little reason as possible to care about them. Thats accomplished by never stepping out of line. Those willing to live their lives that way will be indifferent to the loss of privacy because they feel that they lose nothing from it. Above all else, thats what a Surveillance State does: it breeds fear of doing anything out of the ordinary by creating a class of meek citizens who know they are being constantly watched.
