(One should also be cognizant of Buffet's "when the tide runs out, you see who's been swimming naked". While I don't think he meant it in this way, "genius is a rising market" and when the market goes down a lot of scams are driven out into the open because they can no longer keep their game afloat.)
In general, great efforts have been made to paint hedge-funds as eeeeevil, but with little to no evidence that I'm aware of (note Madoff was't running one ... in fact, didn't he make a big deal about his very low management fees?).
And I don't see how this is related:
The ostensible purpose of this legislation is to decrease systemic risk.
Preventing smaller investors from making necessarily small investments in whatever by definition isn't going to have much effect. The issues are big numbers, not small ones. And how does the 120 day delay fit into this???
Devolving the regulation of these investments to the states might in theory help, not that the SEC is a whole lot more useful than a potted plant (cd Madoff).
Regulating VCs as hedge-funds makes no sense whatsoever (that's not a point you're making, but I can't help but wonder if they're related).
