The rocket science is not a rocket science. Meaning that we sometimes habitually consider something hard because it used to be hard, or it became known to be hard. But with time passing, sometimes things like that change. The literal rocket science is a prime example - we reached orbit in 1957 using technology which is very modest by today's standards. It's still hard to launch a satellite - but it's so, so much easier. Knowing that, SpaceX approach suddenly becomes practically the most logical.
