Decentralize does work when state doesn't matter. Look at tor for a example. When state matters federation is a better match such as emails. The real problem with executing decentralize/federate is it runs on the backbones of a centralized design network. IPv6 helps with that problem, but still at the end of the day dealing with all the complexity, headaches, and unknowns it is more simple to build a centralize solution then spend the extra time and effort for a federated/decentralize solution.
