But the other hand, even those who broke even (or even came out ahead) were still "harmed" by Prosper's illegality, because had Prosper made truthful disclosures, they might have invested the money elsewhere and made far more.
And we arrive, full circle, at the reality that most retail "risk capital" deployed during this time period would have been destroyed by the overall markets, so, even the guy who lost 4% in/on his not-properly-ex-post-facto-registered Prosper notes would have (80%) taken a greater haircut, anywhere else.
So if one plays "woulda, coulda, shoulda", one is doomed to infiinite regress, on both sides, of what, in reality, "didn't" happen and what we can't know.
Ergo...
