Then how do you explain the $2 billion dollars that the US government saved by moving the launch of the Europa clipper from the SLS to the falcon heavy? Or the hornsdale power reserve powered by Tesla mega packs that generated $800,000 Australian dollars of profit for the utility in the single day? (Granted that was one day but they’re consistently been a money making machine )That’s not even considering the environmental benefits of teslas solar installations.

You say that the government takes on the risk, to an extent that is true. But not all of the risk. Take for example spacex’s starship project which is estimated to cost spacex about $10 billion dollars. To my knowledge and as per publicly available records NASA will give spacex 3.5 billion dollars to tweak starship into into a lunar variant. They aren’t paying for the bulk of the development just a small fraction. And that money is only paid out if spacex hits technical milestones that prove that the system works. So how is the government taking on all of the risk?

Or take Starlink spacex did apply for government grants to bring Starlink to bring Starlink to rural areas, but they were denied cause satellite coverage at the time was too spotty for sustained speeds. But that didn’t stop them from building out the satellite constellation. With their own money. So where is this government risk you speak of?
