Bitcoin is a one-to-one implementation of Rothbards property rights and his notion of ethics. Mining corresponds to the original appropriation of resources (mixing ones labor with the soil) and transactions correspond to the voluntary transfer of these resources.
The difficult process of proving ownership in the "real world" is done automatically and implicitly by logging the transaction history in the time chain, tracing back the current property (coins the UTXO set) back to its original appropriation.
Criminal and unmoral actions can only happen outside of the protocol (e.g. steeling someones keys) and therefore Bitcoin in itself is a purely ethical system.
