Also not true in the case of bitcoin. If I want to transfer money to you I don't have to do it on the chain. I can send you the private key of my wallet in whatever way I want and now you have the bitcoin, zero tracking.
That's not transferring the bitcoin, that's giving potentially temporary shared access to the bitcoin.
The other party then needs to transfer the bitcoin to make sure the original party doesn't use it.
