SpaceX does the testing before launch too. They test their engines and stages more than about anyone else. They are less conservative in their designs, so they push the limit with integrated testing.

Speaking of "tossing money in the ocean", tell me again how much money "literally everyone else" has spent so far on their rockets? Like, how's the Boeing Starliner doing? How much money is the SLS program saving taxpayers?

if SpaceX is doing it so wrong it's interesting how they're managing to build the most advanced vehicles cheaper than anybody else. hmmm
