An increasing number of relationships are happening purely remotely. My company went fully remote due to the pandemic and I've started building working relationships, and yes a friendship even, with new employees completely remotely. And I'm a millenial who remembers a distinct separation between the online and offline (and the modem tones lol). (Though I was a very online kid and have made many internet friends over the years.)
Younger relatives of mine don't see as strong a separation and they have friends who they made in primary school that they stayed in touch with despite families moving a long ways away because of how easy remote communication is these days; when I was a kid moving locales meant a new set of friends. It's this demographic and this world that I think is poised to enter VR experiences en masse. Gen X and older Millenials probably still have too strong concepts of "offline" and "online" (and usually prioritize "offline" over "online") to break this barrier down (as you say, a quintessential part of the "offline" experience is snuggling with your dog or an SO) but I'm pretty confident that younger folks won't see this distinction as pronounced. I might be wrong of course.
