The difference is in scale. For the cost of the SLS program, which is likely to be scrapped next year, you could fund the entirety of SpaceX to this point in history. It’s also in success rate, SpaceX within the next five years will have more successful launches than any other space company or organization. They’re already more prolific than any conpetitor with a viable launch vehicle, except Russia.
The problem isn’t so much new vehicle takes time, it’s the bullshit spacex fanboys spout about every other rocket company for doing the same thing.
