NASA in the 1960s ate almost half per cent of the entire US GDP. (The Manhattan project was even more expensive: see https://sgp.fas.org/crs/misc/RL34645.pdf).

Today, that would correspond to more than 100 billion USD a year.

SpaceX has nowhere that kind of money. They are orders of magnitude smaller, and must comply with regulations that Apollo didn't have to.

Of course Usain Bolt will overtake a well trained mouse.
