To play devil's advocate here, do you really think the actual problems with VR have anything to do with "spending time in a made-up universe"? In the future, why couldn't we have VR that didn't require you to wear a headset, that felt, smelt, looked and tasted just like the physical universe in every way? Would it really matter that the VR universe is "made-up"? Sure, that technology is far-off, but isn't it "just" a technology problem?

I can't begin to imagine what kind of technology we'd be talking about here - other than some kind of implant that effectively hijacked your entire central nervous system.

Beats me, but we're dealing with pure hypotheticals here.
