> While governments might not prefer anonymous payment methods to exist, they can still recognize that much of the money-using public appreciates anonymous payments at least some of the time.

To the extent that "governments" don't like anonymous payment methods, that's mostly law enforcement/security agencies.

Central banks basically recognize that anonymous payments mechanisms will exist, and prefer that central bank currency fill that role, since the more non-central-bank money is used in practice, the less predictable effect central bank monetary policy has.
