It comes down to the fact that some problems need outsiders, whose thinking have yet to be confined inside that proverbial box, in order to attain the correct solution
SpaceShip One touched space and all elements were recovered and flew to space again.
BO's demonstration is more publicity than practical rocketry. It doesn't look like the aerodynamic elements of BO's current rocket are suitable for recovery after orbital injection, just after a straight up-down space tourism flight with no potential for orbit, just like SpaceShip One (and Two). They can't put an object in space and have it stay in orbit. They can just take dudes up for a short and expensive view and a little time in zero gee.
It's going to be real history when SpaceX recovers the first stage after an orbital injection, in that it will completely change the economics of getting to space and staying there.
