Maybe if your digital currency depends on printing out private keys and storing them in bank vaults in order to be secure, its security model is kinda shitty? Why should secure digital currency be 100x more cumbersome to use than a credit card?
BTC happens to be worse currently, but not by that much.
EDIT: Also, this is the same model as PGP/GPG and priv/pub key protection. Presumably you don't think this security model is shitty for the myriad of uses it sees.
