What's old is new again - this is why the SEC was created if I'm not mistaken. People were losing their shirts investing in shady companies so the government stepped in to protect people from themselves.

Why do we allow people to buy unlimited lottery tickets or gamble everything away in the casino? Those examples have cleary less benefit for society then the dumbest investment strategy. Let people invest, sure tons if people will lose their shirt but they will learn from it and stay away. Everyone else in the soc…
Soviet Union famously regulated this very well. These luxury goods were only available to accredited investors aka the Party elite.
It seems to me that back then this behavior was condemned by the people of the Land of the Free.
