Me neither tbh 😂

Sure thats fair we don't know if Satoshi ever had other addresses that we don't know about, but thats anonymity and doesn't change the fact that their transactions are not private. It would be ideal to have both.

As an analogy imagine being able to read the incoming and outgoing texts/calls of a random number. You might not know who they are at the moment, but over time you'll get enough data to narrow it down and figure it out.

But the subject was buying from Coinbase (requires KYC) and CJing is not the case by default with BTC. Most users just withdraw without ever coinjoining much less every transaction. Or they few naively coinjoin and then consolidate. And still plenty of privacy leaks even if you do coinjoin because it is just obfuscation not encryption.

Yea, if the FBI wants you bad enough you might be screwed, but why give them passive surveillance over everyone? Make them have to actively work for it. That dramatically increases time and effort required which massively shrinks the pool of users they could ever go after.
