I want to have both options because traditional folders and a tag based file system solve different problems.
Let's say I go on vacation with my dog and make pictures. After I am home again I want to sort the pictures but then I have a problem: the pictures in which you can see my dog in belong into the '2019 vacation to Bavaria' collection _and_ also in the 'Best pictures of my dog' collection.
I'd love to have some sort of universal file-database where I can store all my "final" images and then create collections by adding tags.
How much "chatter" do you really need to coordinate something like this?
If it is a small group of just half a dozen people you should be pretty much invisible if you act a bit clever. Coordination can be done via throw away sim cards and personal meetings so you don't really need to communicate that much.
Hacker News should automatically add the size in MB for each submission. This would a) act as a warning for mobile users (the BBC article about dark matter on the front page at the moment killed chrome on my phone because it has too many images) and b) acts as a wall of shame.
But what I want is different:
I want a universial "DB for binary files" where I can store binary data and all its metadata.
Then I can use this DB to build a app for picture galleries, music collections and tons of other things.
This DB should also support:
* automatic checksumming so that I can detect data corruption
* Some sort of version history so that I can store multiple versions of a file
* there could be built-in replication which I can use to see the same data (or parts of it) on all my devices
