The main difference between crypto and stock markets is that individuals are able to actively contribute to the development of crypto asset while stocks are intended for exactly what you described.

Another way to look at it: consider an investor vs the individual who buys stock but also works in the company. If decisions are made by shareholder voting, the person who works in the company has (or used to -- labor unions) an influential weight regarding operation. It has never been enough to outvote the investors, as we live in a society where Money is King, but that doesn't need to be how crypto works -- crypto organizations require lots of work and they pay for that work without a central authority. It's lovely, really.

I think the medium we need to find is a way to make it so X number of "workers", perhaps 85%, perhaps 55%, to be determined, but this number of workers can outweigh all investors combined. This means that investors will have to seek the approval of workers to get something passed.

Regarding new users, I think you're right. Individuals and groups should have to build trust and respect through work. As they produce work which benefits GRC as a whole, they are rewarded with weight, in whatever form that might take.
