Way to pick out a non-central point. But the answer is that cash and bitcoins are intrinsically self-authenticating but not owner-identified and do not rely upon a credit card / bank-account facility which can be shut down by authorities if it is being misused.
Here's a thought: if you bought Bitcoin with Fiat it is 100% identifiable to you. Please learn about blockchains before you talk.
Your real identity isn't in the blockchain. You can only be identified if the identity of whoever you bought from is known, they know your identity, and they can be induced to share it, or if the transaction can be identified and you can be tracked from the transaction.
