It’s a very tempting idea, but in your model, each founder now has 95% vested in other companies than their own, meaning that they will start spending much more time on other businesses than their own (the brain follows the incentive) which means that they basically give up on their startup. I think this model is flawed (but again, very tempting).

I don't see that as explicitly a bad thing.

If a rational founder thinks they can gain more by working on their friends startup, it might be better for the collective to have more people working on the more promising project.
