For "metadata" read "your entire itemised phone bill". I think the layperson will grasp the implications of giving those to the NSA.
I would sure like to believe you are correct, but I fear the layperson is much too busy (working to pay bills) to pay attention.
I do some random informal polling amongst the working class, my people, and even the most cerebrally capable lack either the will or the investment of time necessary to understand they're slowly boiling the water we're all in.
I am afraid those of us with inclination will have to speak a little louder to cover for our silent brothers and sisters.
