The regulations are not really in place to protect "the poor from their own stupidity." The regulations are in place because the lesson of the Depression is that one person losing their shirt is personal responsibility, and that's fine, but millions of people losing their shirts at the same time will pull the rug out from under the wider economy and be a societal disaster.

The criteria for accredited investors is a very crude way to address this problem by reducing blast radius; we could come up with something more convoluted like requiring a minimum amount of bond posted to act as a floor (similar to how non-insured people driving cars works in some states) but the effect would be roughly the same.

Even if that was the case the hyperboly is put in a way that it's undermining the greater point.
