It's not a matter of safety right now, they are exploding before they get to fly. I think at least two burst during pressure tests, and the last one exploded during a test because the fuel connection to the rocket leaked or broke in some way. The stuff breaking right now isn't really representative of the final product, it's more like problems in ramping up the manufacturing. And the nice thing about reusable rockets is that you can test them much more thoroughly than if you throw them away after each flight.
