It is easy to create a crypto currency that is not vulnerable to sybil attacks; define a central authority. The source of the sybil weekness is not being a crypto-currency, but rather being a peer to peer system.

A central authority isn't really required (depending on your definition of "central authority"), just a connection to at least one semi-trusted node. For example, Blockstream Satellite.
