This comparison doesn't make sense, the USD 200B/year was to invent the capabilities, do trailblazing work on something that needed to be proven even feasible as a concept, to do fundamental/foundational work, not to productionalise technology.
I'd expect SpaceX to do much more now than NASA in the 60s if granted USD 200B/year, considering they are already standing on the shoulders of giants.
