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.
People entirely avoiding centralized regulated entities that harm bitcoin is also a kind of utopia we may never reach. Both promoting avoiding centralized exchanges subject to government policies and promoting the usage of bitcoin as a medium of exchange implies fighting with established narratives, status quo, and governments themselves, so that all also may take decades.
For example, we are consistently warning people about the dangers of using wallets that directly collaborate with chain surveillance firms. Yet, not only don't they stop using it but also participate in signature campaigns and write positive reviews about these surveillance tools. It may take decades to convince people since, unlike Wasabi Wallet devs, you don't and will not pay people to adhere to your views.
