If you don't control your own private keys, you don't have any control of your own money. Satoshi certainly did not think using light clients while controlling one's own private keys contradicted the principle of "peer-to-peer electronic cash".

No matter how you try to spin it, you can't make a future where the vast majority can't control their own private keys sound consistent with Satoshi's vision, or rewrite the public statements Satoshi made about how Bitcoin should scale.
