The revolutionary bit is you can raise money through a DAO without paying millions to a corrupt investment bank to handle your IPO. No letting the investment bank set the opening price too low so their stable of institutional investors get a reliable "pop", etc. You don't need to spend millions on special consultants to help you prepare regulatory filings. So far, anyway. I'm a major crypto skeptic, but I definitely see the appeal of disposing of these gatekeepers and putting the public back in public markets.
