You're taking a backwards-looking view of this.
Imagine if ancient man, living in the woods, saw people of today living in cities. "It feels very uncomfortable seeing all of these people isolating themselves inside buildings".
In fact the very opposite is the case. Now, we go into nature to isolate ourselves.
In the future, going into virtual reality will be where you go to interact with others, and you'll take the goggles off to isolate yourself.
There are enormous advantages to living (as much as possible of) your life in VR:
- your home can be arbitrarily large at zero cost and without taking any land away from anyone else
- you can change the decor whenever you want at zero cost
- you can paint walls as ornately as you like, at zero cost, immediately, without even any prep work required
- you spend zero time on travelling
- you can instantly hang out with friends in foreign countries for free without even needing a visa
As long as the technology is good enough (and please remember that qualifier, because people normally respond with an implicit assumption that the technology is not good enough) - as long as the technology is good enough VR is strictly better than current reality.
