That's just hand waving. The vast majority of people with capital will only ever be willing to invest based on expected returns. If they don't have a chance to make a significant profit on a risk-adjusted basis then they won't invest at all. They'll just keep their cash in the bank or spend it on consumption or real estate instead.

Yes, if the only option you can imagine for building a business is to go the traditional investor/VC route, then this is probably true.
Kind of odd, though. You actually introduced the idea of "regular investors" being some sort of requirement, when the whole point is to re-imagine how we build businesses.
But, I suppose all new ideas—especially disruptive ones—appear as hand waving, given that most people are unable to imagine beyond the status quo.
