Are we referring to the right to exist in ancestral lands where largely, the only claim to such lands are a millennias old religious text? The current occupants of said land have actual, clear historical precedence rooted in fact to occupy said land.
Also, as others have pointed out, I think it's pretty clear that Israel could exist anywhere. The concept of a nation is largely driven by the shared collective of human experiences, culture, norms, and beliefs of the people that inhabit said Nation, not geographical boundaries.
Why wouldn't it be? I don't understand the point of this article. It's not like some other direct P2P communication medium is going to come along and upend it. It doesn't really make sense to run fiber inside your home. You don't need that kind of bandwidth for such a small number of devices and it would be prohibitively expensive since you need a specialized, highly trained technician to run it - unlike Ethernet, where any sufficiently motivated person can do so. I've heard that the people that run fiber for ISPs make something like $200/hr or so.
