I know you’re not really engaging with the argument here, but IMO I'd like to see more early capital directed by agencies that are ultimately accountable to democratic bodies. Plenty of examples at DoE
The CIA has long had a "VC" arm; I think it's inevitable that there will be climate and energy investment funds (more like agencies) directed by DoE, DoT, and whatever Department gets created when the US finally decides to tackle climate change at large.
So I think you'll certainly get your wish but it's a matter of when. Until then it will be a small amount of informal control through a sort of cronyist "you owe us now" type pressure.
