@aekis_projects From my view, with all the dreams, I have had, it is hard to say whether this goal is worthwhile.
But what I can say is that if you have an engineering goal of building human cities on the Moon or Mars, you're going to need a huge payload to orbit capability. Not just per launch but per year. And NASA, through their partners Boeing, ULA, Northrop Grumman, and Aerojet Rocketdyne, has not even remotely delivered that with SLS - a rocket which will launch once every few years at best, at over $2 billion per launch.
The only organization with a clear path to such an annual payload to orbit is SpaceX. And blowing up one rocket is not a sign of failure, it is a milestone on a development process they chose with intention.
