Split transactions up, mix them and recombine them? State actors could do that extremely easily. They’d have entire tech teams and processes for managing those flows

“Let’s make bitcoin less useful as money in hopes that it will deny privacy to the government!” With this attitude, Bitcoin will never be money.

I've implemented bitcoin payments and Monero payments for the hardware devices I used to produce. Bitcoin is definitely more useful as money. And it's not "in the hopes" of it denying privacy to the state. If we assume the end state is total replacement of the financial system, it makes sense that the base layer is completely transparent and privacy exists in layers on top of it, rather than the other way around (which is how the fiat system works). In the fiat system, the base layer is not public, and the outcome of that is oligarchs etc have privacy but individuals do not. Take like a year and get to the bottom of why that is.

No they can't. Do the math.
