Using a currency with a permanent, irrevocable public ledger of every transaction for anonymous payments?

(I assume you mean BTC here, since very few places actually take privacy coins like Monero.)

I would never use BTC purchased directly from an exchange to make anonymous payments. If a vendor only accepts BTC and I want privacy I normally swap it for monero then back for BTC again to remove any connection to me.
