A good ELV is all that ULA require in the immediate future to meet DOD and NASA missions. The govt is still their main customer and they will not be demanding RLVs anytime soon, especially for their more expensive payloads. When comes to commercial customers, Vulcan only needs to be more competitive than the ELV competition eg Ariane 5or6 and Proton.
Yeah, 2hr turn times will require a much more advanced vehicle than what SpaceX is doing, and the right kind of payload. A $1B satellite with <1day turn around time? Doubtful anytime soon.
