The benefit is that you can only trust in person interaction with social and governmental institutions so people will have to leave their damn house again and go talk to each other face to face. Too many of our current problems are caused by people only interacting with each other and the world through third parties who are performing a MITM operation for their own benefit.
Over the past century and a half, we've moved into vast, anonymous spaces, where I'm as likely to know and get along with my neighbour as I am to win the lottery.
And this is important. No, it's not just a matter of putting on an effort to learn who my neighbour is -- my neighbour is literally someone whose life experiences are wildly different, whose social outcomes will be wildly different, whose beliefs and values are wildly different, and, for all I know, goes to conferences about how to eliminate me and my kind.
(This last part is not speculation; I'm trans; see: CPAC)
And these are my reasons. My neighbour is probably equivalently terrified of me, or what I represent, or the media I consume, or the conferences that I go to.
Generalizing, you can't take a bunch of random people whose only bond is that they share meatspace-proximity, draw a circle around them, and declare them a community; those communities are _gone_, and you can no more bring them back than you can revive a corpse. (This would also probably not be a good idea, even if it were possible: they were also incredibly uncomfortable places for anyone who didn't fit in, and we have generations of fiction about people risking everything to leave for those big anonymous cities we created in step 1.)
So, here we are, dependent on technology to stay in touch with far-flung friends and lovers and family, all of us, scattered like spiderwebs across the globe, and now into the strands drips a poison.
Daniel Dennett was right. Counterfeit people are an enormous danger to civilization. Research like this should stop immediately.
