Of course it is hard to argue that, It is much better learning that you shouldn't have designed your rocket with a particular flaw than the alternative. The alternative is not designing your rocket with the flaw in the first place, using only known and proven technologies, avoiding risks at all cost like gobertment(NASA, ESA) agencies do. And this is very costly in the long term, because technology does not improve.
