If only people with something to hide used encryption, then using encryption would mean you have something to hide.

Of course, the factors used in making your decision of whether to cross the border with encrypted data change as soon the consequences change. If they can lock you up for not providing the encryption key--as they can in the UK now, I believe--then the moral argument quickly becomes less compelling than the practical one for many people.
