In what way is socializing with others in VR "isolated"? Real people interacting in social VR applications with other real people are not isolated. In fact, I would argue that they're less isolated than people who can't interact with humans from all over the world, and are only exposed to the same group day in and day out. P.S. are blind and deaf people "isolated" in ways you think make them unable to enjoy social interaction? That's a very narrow approach.
