Your arguments are essentially shifting blame from the fraudster to the victim... not unlike the kind of arguments that suggest certain rapes or murders are also the victim's fault for either dressing suggestively or travelling through the wrong part of town at the wrong time. While those things may actually be unwise, that the victim didn't act with wisdom or prescience doesn't relieve the perpetrator of culpability nor make the victim deserving of such violation. Wisdom merely dictates that it might be better for you to avoid the risk of becoming a victim if you can.
I personally don't engage in these kinds of financial instruments because I feel the risks are pretty high.... but I absolutely applaud the government pursuing a fraudster where ever they can... without regard to the wisdom, or foolishness, of the victim.
