No. Bitcoin is fungible. There are no dirty coins, there are only people claiming they provide a service which can de-anonymize the blockchain to an extent, and which is evidently inaccurate and based on utter guesswork.
You're wrong because bitcoin's fungible that's the way Satoshi created it. Bitcoin's got nothing to do with identifying dirty or tainted coins on the blockchain. Bitcoin was created as fungible that can't be denied but if we're talking about govts wanting to control crypto by regulating it's a separate point.
Yes. That's what I've meant. Please excuse the typo. If each Bitcoin were non-fungible (unique), it would be a hell of a lot easier to identify tainted coins. With BTC's current state, governments can only guess which coins belong to whom and where. They've censored centralized mixers hoping people don't get access to privacy.
Would you imagine if developers added ZKPs or other privacy technique to Bitcoin? That would create a lot of controversy, possibly resulting in mass delistings from mainstream crypto exchanges. With institutional investors getting in the game (Blackrock, Fidelity), it's best to keep Bitcoin as is. If you want privacy, just use a non-custodial mixer or a privacy coin such as Zcash or Monero. Lets hope BTC stays decentralized forever.
