Even beyond entertainment, when working hours in an office, I'd rather look at a beach or fantasy landscape with a nice ambient sound than a dull wall with rain under a greyish light outside. I'd likely spend most of my time in VR just because it's nicer.
Life-like VR fundamentally holds the promise of being one more great social equalizer if you can essentially simulate material wealth (objects, locations) like a video game, even just the visual part of it. E.g. IKEA is all over such research, with good reason.
Most people also don't realize that in terms of communication, any non-physical interaction (so excluding sex and hugs) would be just as good in VR as in reality, thereby making face-to-face meetings the norm anew (like before any form of distant communication existed, save for mail). That's bound to be a healthy change, a welcome improvement from text, audio and even video.
It's just a little bit too early indeed, and probably headed for a (shorter) winter I agree. Come 2030ish we should have much more decent options to move forward (from current specs you'd estimate a 10x at least to reach 'acceptable' capabilities, and more like 100x if you seek visually life-like sim, i.e. ~250px per arc minute at 100Hz or more over at least 180° field of view).
