That's not what the post you replied to said at all and you are being intentionally obtuse. There is a reason the SEC exists. It's not to keep people from making bad decisions.
I think the issue is assuming people who get scammed are at fault for something, just because a more paranoid person would have avoided the scam.
Regulation will not stop me from selling a potato for $100. it will stop me from selling a regular potato for $100 while claiming it cures cancer.
Buying a potato for $100 would be dumb, and nothing stops me from doing it
Buying a cancer-curing potato for $100 is not dumb. Believing a potato can cure cancer because someone else is publicly selling it to me that way in full view of the entire world is not dumb. I would think "oh wow, something about this potato must be cancer-curing because surely this guy knows that if he scams me in front of the public then the public will hold him accountable."
So it is now time to hold people accountable
Basically, it's exactly that.
Now one can be informed but also choose to make stupid decisions. People do this all the time on penny stocks, options, etc... The SEC has no interest in trying to stop them, just making sure they know up from what they are getting into.
Other than that, lies and manipulation are part of the equation. It's a bad decision to blindly trust anyone or anything. You can't separate smelling bs from judgement.
The whole concept of an accredited investor is basically saving people from themselves.
The SEC has a pretty ill defined set of risks they are trying to protect people from. People will find ways to lose their money if they don't have a general "wait, do I have a clue what I'm doing here?" filter.
