How could a robust decentralised file system be useful?
Would you use one if one was available?
If so, to what use (storing, sharing, building apps on top of it, …)?
If not, are there some specific reasons like difficulty to set up, legal, you already use one, or other?
I’m making one and it is fully functional but adoption is not here yet so I’m trying to figure out why.
Cheers
Edit: I’m referring to a decentralised online storage, accessible from anywhere.

Is it a matter of everyone having a copy of every file? Or is there some sort of limit, like, a certain amount of people connected having a copy being deemed enough to ensure that it will always be available?
You decide, so if you want a redundance of 10 for example, you’d share ten (similar sized) files and ten others will share your file.
