Should the government be handed every transaction on a silver platter every day? Probably not, but I don't think you'll find many people in the big wide world agreeing that financial activity should be forever unavailable to governments, courts or anything else, even under applicable warrant, which is what these services provide.
And why is this absolute privacy bad? Where to start? Criminals hiding ill-gotten gains is only a small part of it. We have the funding of rogue nation states and enabling of ransomware, which is roughly in the same ballpark, sure, but very harmful. Then we have straight-out tax evasion. We also have dictators and despots who plunder their countries and enrich themselves. Should their activities be private? Should we just allow them to siphon money off to other countries and live the high life while their population suffer? It happens all too often already, but in much of the west now we are catching this stuff and denying them those things because we can see some of what's gone on.
And what about our own democracy? Absolute financial privacy can allow wealthy interests to brazenly buy politicians, with guarantees of untraceability.
So no, I don't "realise" how tyrannical and dystopian that is, in fact to me it looks like it helps prevent a variety of forms of dystopia, in which the rich and the corrupt could even more easily and directly buy democracy out from under us.
The fact that you can't currently have a system which provides privacy until an authority (such as the court system) demand things be unlocked, well that seems like a problem for cryptocurrency users, not the law.
