I'm no believer in immortality, but I find your argument unconvincing. People are removed from their childhood home all the time, immersed in a foreign culture.

I'm no believer in immortality, but I find your argument unconvincing. People are removed from their childhood home all the time, immersed in a foreign culture. They survive. I'd certainly accept a sudden relocation to an unfamiliar foreign land vs. dying. And I'm certain that a hypothetical resurrected human wouldn't be the only one - what's to say these folks wouldn't form their own pocket of culture?
