1) That's debatable. Companies are after all just people doing stuff. You don't own the people and they could all just quit one day. Maybe you own a part of the company assets, but these days with remote work and internet companies that can be close to nothing. I don't see many stocks paying out dividends, but I suppose that's a thing.
2) Illegal's never stopped anyone from doing anything, and I don't see how the crypto version isn't fraud too. But in both these cases you can fly to a non extradition country with your newfound fuck-you-money, leaving the investors up shit creek without damages.
Crypto has some benefits over the stock market, it's open 24/7 so it doesn't discriminate against anyone, and it's more volatile so one can get higher returns (well, or losses) with less of an investment without having to resort to options or margin which are just as risky. It also has more defined and predictable bull/bear markets in relation to bitcoin halvings.
I don't really see the two markets as too different though. One has just had more time to become more rigged for wall street.
