The SEC alreadyhad rules for selling unlicensed securities. IMO that isn't whistling.
Using the analogy, I'm saying the SEC has rules against "disturbing the peace".
You aren't making any sense.
Of course there are rules against unlicensed securities.
But let's back up.
Which legislation classifies P2P loans as securities in the first place?
Answer: none.
We only have the SEC's interpretation of the "old rules" (referring back to when Prosper tried to convince the SEC that Prosper didn't need to file with the SEC and the SEC answered, "We think that you do.").
Well, anyway, I see ira01 responded as I write this. And a very sensible reply it was!

So that answers it for me. Thanks, ira.
