You could say the same thing about perpetual motion. Being realistic about why past efforts have failed is key to doing better in the future: for example, people won’t mirror content which could get them in trouble and most people want to feel some kind of benefit or thanks. People should be thinking about how to change dynamics like those rather than burning out volunteers trying more ideas which don’t change the underlying game.

What there isn't is a currently maintained and advertised client and plan. That I can find. Clunky or not, incomplete or not.

There are other systems that have a rough plan for duplication and local copy and backup. You can easily contribute to them, run them, or make local copies. But not IA. (I mean you can try and cook up your own duplication method. And you can use a personal solution to mirror locally everything you visit and such.) No duplication or backup client or plan. No sister mirrored institution that you might fund. Nothing.
