My argument is that the rich have been evading paying taxes for decades and the IRS acknowledges this. They also acknowledge that they actively target the poor due to auditing the rich being difficult. I am sure politics and lobbying adds to that difficulty.

The current system is geared towards keeping the rich and poor where they are. I find it interesting that the IRS devotes resources towards targeting a new wealth source available to the poor while not dedicating those same resources towards auditing the wealthy. (I am in no way a crypto evangelist). One could argue that they are going after low hanging fruit, and I would not disagree but I would also argue that they are actively choosing to not target the rich with their limited resources.

I think you analogy is flawed, I would instead compare this case to the police hanging out in poor neighborhoods targeting house parties vs doing the same in rich neighborhoods as they may need to go the extra step of getting a gate code to the rich neighborhoods.
