so... are you saying we should ditch roads and mail and electricity and water? Your response is one of the sillier non sequiturs I've seen in a while, and I browse Reddit.
My mom didn't have a telephone, she had other friends without telephones, but having a telephone when she was a kid was fundamental to building robust social relationships. The reduction of social bandwidth generally results in fewer opportunities for social advancement, and most people would like to experience social advancement of some type.
That is not obvious at all. I think it's not even true.
Social networks are not valuable for me, and they would not improve my life. I don't want to use them, and I don't.
It's that simple, really.
do you realize that using the mail service is optional? nobody forces you to write post cards.
do you realize that electricity is optional? you can get a shack in the forest and burn wood.
do you realize that water pipes are optional? you can dig for your own ground water.
the world is not made of solipsistic individuals. infrastructure encases, shapes, and forms the possibilities and constraints in which all of us live.
