I think the minimum NW change is the most minor of the issues here (especially in SV). Imposing more of a regulatory burden isn't going to make anyone more likely to cut checks, and increasing the barrier and latency to initial funding is going to make plenty of potential entrepreneurs decline to make the leap.

I think it's quite dangerous to assume such provisions aren't going to make it past whatever partisan wrangling goes on; I doubt either the dems or the GOP are going to give much of a damn about the startup ecosystem unless a lot of noise gets made about it.
