Somehow I don't think many people will be willing to store arbitrary data like this on their hard drives. It only takes one person to inject something illegal before the entire blockchain becomes incredibly dangerous to handle. There's not really much worthwhile in storing something in this expensive format over an http/ftp/gopher server server if it's not illegal in some way, which will probably lead to it being quickly unsavoury.
On the technology side, you'll get to the point where no solved blocks include any data because it's causing massive orphans for the miner. I can't see this ever working the way the author intends. That already happens in the bitcoin system where blocks are extremely well compacted, and still people don't want to include transactions against the risk of losing their income.
