Bitcoin works right without "the internet" or even an IP network, you can sneaker net around the Blockchain, if you like. But indeed, Bitcoin-- and the technology in it-- doesn't generally solve the hard problems the web presents (just like the prior distributed system technology before Bitcoin didn't solve Bitcoin's issues). There is a lot of seriously misplaced hype in this space. A bit of pedantry on your last comment: "The biggest problem with the blockchain is that every (at least veryfing) node need a full copy of it" -- this isn't true. Please see section 7 of the original Bitcoin whitepaper "Reclaiming disk space". It's still not a suitable mechanism to store arbitrary data, however.
