It's like they don't know where the car is, only which it is, and put the vin in some stolen car database.
Bitcoin seems so terrible privacy wise. It's so much more traceable than cash. I don't know why people don't just use monero. That'd be like everyone on the planet drives the same car, and the only way to identify yours would be to have the keys to it. The analogy works because monero takes a long time to identify yours with your key - you have to check every "car". That's one of the major technological downsides to it unfortunately.
