You're not getting the point.
How about this. Me and my gf wearing VR headsets playing a game where we sit on a couch in a house on Mars looking at a virtual TV where another game plays.
The point is, if you're not seeing the potential, fair enough, but you are basically just repeating Nintendo's opinion on a matter. What's Nintendo's opinion on social net-works, text messaging, do they believe that photography will steal your soul? Don't let us start a discussion about ethics here, there are people out there who won't distinguish between isolated and social gaming - for them gaming is bad no matter how you turn it.
Progress gives a shit about ethics and those who won't accept progress will simply be run over it, if you like or not.
So, you think that Nintendo is just waiting for the right moment? Aha, so in the same way they've waited for HD and Online gaming? No fucking company on earth can come late to the party and just start competing in an advanced tech sector. Ask MS how many billion dollars their entry into the console business did cost them.
Respectfully, if you and your girlfriend had a child, the idea of wearing a headset would be much less appealing. The appeal of VR is real and obvious, but the isolation factor of HMD is significant enough that it cannot be hand-waved away. It's not so simple as to say that everyone else can just join you in VR. The immersion of HMD VR can only be responsibly enjoyed if everything else in your life is compatible.
