There has been several projects that have tried RWA's, but nothing has been really successful so far because of regulatory limits with trading securities. And you do understand that we literally already have such investing opportunities, by investing companies with stocks? They aren't just decentralized, and making them decentralized often falls to ever changing regulatory demands, and lack of the platform that operates in a way FATF would be happy about it.

You can't just create a erc-20 or other token and say they are company shares or rwa's... Well you can but you couldn't even trade them via any legit cex. And sharing company profits to pseudonymous accounts would break AML laws and get you to jail eventually, if amounts were big enough.
