SLS reused a whole bunch of hardware and launched 6 years late, basically doubling the planned schedule and slipping dozens of times. Obviously a clean first launch can be done, I'm not arguing against that, I'm saying "Basic rocketry isn't all that hard anymore" is nonsense. Nobody looking at the SLS program and its troubles and say that building rockets isn't difficult. You can spend an enormous amount of time and resources while using as much legacy proven hardware as possible to try to never fail... or you can blow up rockets to test them for faster cheaper results.
