The thing is, nobody is born sophisticated and there are many ways to get hurt in financial markets in the absence of scams even if you're intelligent and do your homework.
You mention index trackers, but they are no silver bullet. Their mechanism is basically to buy more of stocks that go up, and to sell those stocks that stumble badly. The more people rely on index trackers (exchange traded or not) the more volatile they'll become, and because index funds use such a simple trading strategy it's easy to front-run or otherwise exploit them. Furthermore, index trackers depend on active investors for price discovery, and the fewer active investors you have the worse index funds will perform. Relying on a vanguard ETF might continue to work, but to assume that it will is hopelessly naïve. It's no coincidence that ETFs got so popular with interest rates at 0 and a fed that made stonks go up.
The questions are rhetorical. Companies will rob their shareholders blind if you let them. You can't just be "lol caveat emptor".
(Casinos also cheated players shamelessly in the good old days before regulatory oversight.)
But, I'm really not getting your point here. SPACs have to report financial results just like any other public company. They aren't allowed to commit fraud any more than any other company.
Lordstown Motors. Faked their order book. Blatant securities fraud.
There are many others.
Imagine I buy a chainsaw which is clearly labelled as something that can cut your hands off, it's widely known and obvious to everyone that chainsaws can cut your hands off very easily, not just in the specialist financial press but also on comedy shows and from TV news pundits and loads of other sources - I'm a mentally competent adult, I'm informed about the substantial risks, I want the chainsaw anyway so I can chop down lots of trees fast. Then I chop my own hand off by mistake.
Was it society's responsibility to protect me from my own mistakes, even when I was fully informed of the risks?
It's like giving 40% of the adult population a chainsaw that they have to use if they want to retire at a reasonable age. The outcome is predictable and they would be wise to invest in a prosthetics company.

So what? It's also well known that the IRS doesn't take payment in iTunes gift cards. So do you think if people get scammed, it is their problem for not knowing better? Should we just repeal all the laws against fraud and scams, because caveat emptor?
The behavior described in the GP post is unacceptable, and the fact that someone theoretically should have known better doesn't excuse it.
If people want to gamble, then that is their problem.
