Although I mostly agree with your point, it's worth noting that the same could be said many financial products these days. How many of us really understand the hidden risks of the stocks in our portfolios? Part of this game is trusting what we hear and read, and the proclamations of our institutions and government. In an increasingly complex world (financially and otherwise), it's often hard to know what or who to believe.
Granted, PPNs are confusing instruments and have been less regulated than they should be -- but can the same not be said of AIG, Lehman, and the rest?
