Lots, obviously. It isn't utopia. But not being connected would make you impoverished. Like how monks might disconnect by taking a so-called vow of poverty.

And people who voluntarily do that? Vanishingly rare.

It is interesting that it is obvious to you. Did you grow up in an unconnected region and then become connected later in life? How would your perspective change if that was true. Is this speculation or have you spoken to someone who had that story? I find it fascinating what facts are assumed by societies. That the current way of life is the best is a reoccurring theme amongst societies with very different conditions. To me it is more of a defense mechanism that rationalizes it more than anything else, but that's just my opinion.
