Instead, we should be promoting the advantages of the bitcoin circular economy
I don't disagree, and I regularly speak about the benefits of avoiding centralized exchanges and other centralized platforms, of spending bitcoin directly, of avoiding government regulations, of avoiding services which buy in to this taint nonsense, and so on, but reaching the utopia you describe will take decades, if we ever get there at all. Fighting against taint analysis is something that needs to be done
now. And if we continue to let faceless organizations dictate how we are allowed to use our bitcoin, then we will never reach that utopia.
We can still support the idea of alternative coordinator or some Wasabi fork that would work without any censorship, but someone needs to take risk with this.
No point. Why take a flawed concept and try to mitigate the flaws, when you have non-flawed projects like JoinMarket you can use today.
