Perkeep – Personal storage system for life

I don't really understand the goal here. It feels like "wouldn't it be nice if instead of organizing a library, we just kept all of the information in a giant unsorted pile of looseleaf paper?"

How is this better then a filesystem with automated replication?

The overview is very comprehensive: https://perkeep.org/doc/overview

This desparately needs to be on the main page to explain what this actually does, and not buried under "Docs", which isn't at all where I would expect to find this kind of thing.
