This is an intellectual exercise, not a useful service. It's similar to those schemes for storing MP3 files in Google calendar entries, or whathaveyou.
The txn cost[1] to write any non trivial amount of data to the Bitcoin chain makes it a very expensive filesystem.
Except your Google calendar entries can't be monetized in perpetuity. Remember, every file put on chain is linked to a wallet address. Imagine creating a viral meme and getting fractions of a penny each time it was re-posted somewhere. That's where this is all headed.
