I hate the way the cryptocurrency world has sucked all the air out of the decentralized room. Why does a decentralized app have to interact with a smart contract? We already have tons that do not. Why does it need a coin?
The notion that the concept of money itself is dirty is an antiquated one. If you're not trading money you're trading time or limiting your scope. No approach is inherently worst than the others, but since the money way is new to decentralized networks that's where the innovation will naturally tend to happen.
But if you really don't like money in your decentralized networks I hear the GUN[1] ecosystem is pretty active. In-between solutions like Mastodon[2] are also blooming. And if you follow Ethereum's "leader" Vitalik Buterin on Twitter, you'll see he himself is very supportive of alternative approaches that don't involve cryptocurrency[3].

You post a bounty in the Etherium world that you want some storage, some compute, a name, an address, etc. and provide some gas so that the network can verify the contracts have actually been fulfilled, and then poof, your site is running somewhere.
Or the simpler case which this is trying to tackle, you want to host a site on IPFS but you don't want to buy an always-on node. Choosing a single provider would be "centralizing" in their eyes so you post a contract for people to seed your site on IPFS and get paid for doing so.
Seems like a cool idea.
