> Instead of clicking a button to swing an axe, in VR you can naturally swing that axe with your own hand.
I agree. This is exactly the sort of inconsequential activity where VR will really excel.
> Instead of dragging a mouse to draw a line, you can just move your hand.
Dragging a mouse is "just moving your hand." If you really need less friction in this case, use a touch screen. What do a VR headset and VR hand tracking gloves add?
> In many cases VR allows to skip that layer of indirection between input (keyboards/mice/joysticks) and output (screen).
I like this point, and I think it might illuminate where the fundamental disagreement is: how many of these cases are there? For most of the things I do with my computer (writing code, email, listening to music, reading articles) I am simply not convinced that there is a layer of indirection. Keyboards, graphical user interfaces, and CLIs are already well-optimized for ease and efficiency in achieving their stated goal. Introducing VR would increase friction rather than remove it.
