I haven't followed this specific launch in much detail, but part of why SpaceX has been so successful is they expect a certain amount of failure and don't pin the failure of the program on the failure of any one test. This allows them to iterate faster than other programs that might have less test launches and thus rely more on the success of the launches they do perform. I've heard for example that this rocket is already out-of-date and the next planned rockets already have a bunch of improvements.
