There is more than enough money sloshing around, it all boils down to designing contracts and suitable information exchanges between parties. So anybody thinking that the current system is sub-obtimal can try their hand at disrupting the VC system and making history :-)
An arrangement that better utilizes the majority of the entrepreneurial crowd's energy and time is likely to at least carve a niche, if not dominate. It may not even be that hard. The chasing of planet-scale returns (with the corresponding discounting of the rest 99.99%) is a recent phenomenon and may be just an aberration.
