What's interesting tech what isn't necessarily whats great for end users. Would you trust your mission critical data to a decentralized store? I wouldn't. What's the latency and throughput of Arweave? Can I serve 100k QPS off of it? What happens in the end of a protocol hack or client, bug? We've seen many blockchains destroyed by bugs and flaws, and we've seen others just fade.

I mean, we've already gone through several distributed file stores, FreeNet, eDonkey, Gnutella, OpenNap, etc. They were still attackable by organizations like the RIAA, but more than that, they were slow and unreliable. Adding financial incentives in I don't really think will improve things that much. How many people are running Ethereum clients and yet DApps are horrifically slow.
