I've built KYC tools for crypto transactions. It's possible to do while
maintaining privacy.

Take the FATF travel rule, for example, you log both halves of the
transaction and give the regulator tools to join those halves. This can be
done as a zero knowledge proof that, for a given predicate offense or SAR,
Mallory has engaged in transactions W, X, Y, and Z. Intermediaries can
pre-commit keys that allow the join.

Further, for public chains, this kind of KYC metadata can be privately
attached to transaction identifiers to show Mallory's structured pattern of
transactions (helps de-anonymize OTC trades and build a chain of reasoning
for legal/audit use cases).

Building privacy-conscious tools for regulators supports privacy: it gives
them options other than outright banning or whitelabelling the technology.

Bitcoin isn't under attack -- it's won the battle: the financial system is
adopting it.
