Thus their focus on Raptor, and the ITS using methane and LOX with "hot" O2 and methane to pressurise the propellant tanks. One it look at it as "avoiding problems with the COPV immersed in cryogenic O2" or "replacing COPV problem with hot gaseous oxidiser problems". I hope SpaceX learn the important design lessons in develoment and test flights, rather then six flights into their colonisation effort.
