What you're suggesting is a social consensus on "let's close our eyes and consider every two UTXOs fungible" which I am all for.
I find it pretty comical that you say you are in support of fungibility and and not supporting nonsensical and arbitrary "taint", while at the same time implementing a change in your wallet which does the exact opposite of this and blacklists coins based on completely arbitrary "taint" fed to you by blockchain analysis firms.
Unfortunately, we are a minority who understand the value of fungibility and even a smaller minority who are willing to act based on this social consensus.
Except you aren't acting on this, are you? You are doing the exact opposite with these new pro-censorship, pro-taint, and anti-fungible measures you are implementing to the Wasabi coordinator.
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."
