My reply you were quoting from already highlighted, acknowledged and addressed your point: "In fact, even if there's willingness, the real world may force you to not do that anyway, just like in our case, so we must have technical solutions instead."
Except you weren't actually forced and you instead chose to do this freely, and the only "solution" you have proposed is censorship, which is contributing to and compounding the problem rather than solving it.
I don't know why people keep thinking that Bitcoin has some special kind of taintness, and everything else is so clean and pure.
Because centralized exchanges as well as some entities which should really know better (e.g. Wasabi) are complicit in supporting this nonsense that some bitcoin are tainted and therefore should be censored.
