Governments could easily use private data to blackmail or silence you, even if you’ve done nothing illegal.

This is perhaps the primary reason that the right of privacy even exists.

Governments could also easily freeze bank accounts, even if you've done nothing illegal.

Cryptocurrencies like Bitcoin directly mitigate (if not outright prevent) that risk.

Governments can also violate all your other rights as well. But this completely irrelevant to the post I responded to.

It's absolutely relevant. You replied with one way a government can violate your rights and the importance of mitigating that violation. I replied with another way a government can violate your rights and the importance of mitigating that violation.

Privacy isn't absolute otherwise we wouldn't have CPS.

I did not imply that it was.
