I'm not sure why everyone assumes that bittorrent was about currency. It wasn't, and that was its superpower. No matter how much you were able to contribute, you were able to strengthen its system, redundancy and availability.
The only problem bittorrent had in practice was a legal one that finally led to a problem of availability of discovery.
All that filecoin hype will lead to only one thing, and one thing only: the people that are popular will decide what files are worth to the system, and the masses will simply dump everything else and forget about it.
Add an inflation for every modification of any file in the whole system, and you have a perfect way to destroy real incentives.
I don't believe in most web3 projects because they always think it's about trading files with each other. It is not. Discovery and access to data should not be limited by your financial capability to buy things. The internet exploded because people got access to vast amounts of knowledge, for basically free compared to before.
