The profit-seeking startup can raise $30M with a pitch deck because investors believe it has a good enough chance to return 10x in a couple of years. It's always as simple as that. The business environment isn't the way it is because of unreasonable forces, but because it has evolved to prefer and facilitate the ways of doing business that are most conducive to profit. And Airbnb and Uber's founders' gestures towards prosocial/inclusive governance, if they were ever sincere in the first place, likewise died when it became clear what was needed to maximize profit, etc. And to belabor the point, even if the SEC starts allowing co-op-like corporate forms, they largely will be outcompeted because the form hampers (is designed to hamper) profit maximization.
Of course, maximizing profit through commons-depleting practices is bad. But that badness is likely to continue unchecked, other than in physical commons where the consequences of depletion are "people dying" level bad.
