I said they are "the same" only in terms of how your brain can immerse/rewire itself to understand those new controls as if they were artificial limbs. Even with the same level of fluency, some controls are definitely better than others depending on the domain.
So VR is definitely not pointless. Motion tracking for your head/arms/feet unlock many applications that are previously hard or impossible (e.g., 3D sculpting using mouse/tablet vs a motion controller).
But it's not always better than mouse/keyboard input for let's say typing or shooting a target. Having more irrelevant degrees of freedom makes it harder to master your input controllers, even if you already had a lifetime of practice with it in the real world (e.g., I am okay with doing parkour levels of movement with WASD/Space but won't ever try it with my real limbs even though in theory I know how to climb over a real world fence).
