My goal here is to try and point out that there is a solution that can be rolled out in under 6 months by leveraging existing kyc infrastructure.

You complain of the erosion of privacy, and yet your goal is to give the oppressors tools to justify their actions. Especially tools that you know are far from perfect to achieve the anonymity goal. I'm sure that you don't have bad intentions, but what is happening after is that persons less take savy will take your work as an example that "it is possible" and that technologists are bullshiting them when saying that it is not possible without eroding anonymity. They will not look further than that. Look we can do laws because it is not impossible if we want.

If you look well in UK, this is what is happening, the country trying to give the legislator a reality check, but too late.
