> Unregulated securities are often a synonym for "scams" that is why you have to be a qualified investor.
That's the point though, scams are scams whether they're run by a loan shark or Bernie Madoff. Anyone should be allowed to invest their capital in any legitimate venture they see fit, and anything that meets the legal definition of a scam should be shut down and barred from taking money from anyone.
It's quite patronizing that the government takes the stance of "If you don't have X amount of money, you're not wise enough to tell the difference between a scam, a foolish business venture, and a legitimately risky business venture. Better leave that to the experts (and their commissions)."
