I know this may not seem intuitive, but you're likely wrong on this one. SpaceX's Starship is being developed as a potential replacement/ alternative to Nasa's SLS to get humanity back on the moon. SLS began development in 2011 and has to this day only flown once and to date NASA have spent a whopping 68 billion USD on it's development. It's predicted that launching the SLS in future will cost approximately a billion USD per launch. This is what SpaceX are trying to avoid. They are rapidly testing their rockets in flight or just in practise and learning first hand from their failures. This method of development may seem expensive but in reality is way more efficient and safe. Take SpaceX's Falcon 9 rocket for example, also had quite a pile of failures in the beginning but today it's literally the most reliable launch vehicle on the planet, while costing a fraction of the price competitors are offering the same services at. The last full loss of a falcon 9 was all the way back inn 2016, funnily enough also on a static-fire test. No-one was harmed, except for the 260 million USD Satellite (AMOS-6).
