websites that host the leaked celebrity nudes are torn down constantly

That is true, yet surely most live on as torrents (and discoverable via hundreds of sketchy torrent websites that pop up and fizzle away)? Even before most people had broadband, nerds traded collections of pirated software via "sneaker net"

  internet access will eventually be completely de-anonymized. Social security or gov. ID to sign on.

That scenario seems possible to me, too, and I agree its outcome would make what I envisioned less likely. It's not guaranteed to happen though.
