I think it's just a way to segment people who can afford to lose more. The government wants to protect people from getting screwed out of their money, but can't strictly define "this is good, this is bad." So they just say "okay, you can afford to lose more, so you're (relatively) on your own. Go ahead and invest in those crazy schemes if you really think it's a good idea."
