As always, it's a bad time to be an imaginary person.
It's a big leap to pretend the model reflects the real world, let alone today's real world. As far as I can tell, sharing has become largely fenced into communities (reddit subs, Facebook groups). People who still share with people they know personally appear to me to be a minority.
Don't get me wrong, the principle is sound, but the world changes fast and the described model doesn't seem very relevant nowadays.
