Oh, I'm sure there'd be plenty of crap investment opportunities available to ordinary investors. There's an interesting idea called rational ignorance - basically, investigating an investment opportunity costs time and money, and it's irrational to spend more on investigating it than you'd lose if it failed outright.
So being able to offer poorly-regulated "high-risk investments" to normal people who can only invest a small amount would be a scammer's dream; they can't put nearly as much resources into investigating the investment, or into recovering funds if it turns out to be a scam.
Nearly all the good opportunties will continue to go to a handful of well-connected wealthy people because it's far less work to raise money that way.
