I think one use-case that makes some sense is Mysterium (https://mysterium.network https://mysterium.network). VPNs actually have material benefit from decentralization, and the ability to actually cover costs in operating exit nodes is somewhat of a game changer relative to something like TOR (I do realize they have different security profiles, though). Data storage is also a moderately interesting application. Decentralizing data persistence, and being able to take advantage of the enormous amount of excess hard drive space that exists in the world is an interesting concept. Things in this category are Sia, Storj, and MaidSafe. While i'm not sure the economics and logistics will actually work out, I do think there is something there.
